How Your Brain Chooses What To Remember

During the day, your brain is simply too busy to encode memories without interfering with normal processing. At night, however…

The filing system

The brain decides which memories to keep based on significance, using sharp brain wave ripples as an internal bookmarking system. Everyday memories fade, while important events are tagged in this manner for consolidation during sleep.

How does it do this? It starts in the hippocampus, which records experiences during wakefulness and replays them repeatedly at high speed during sleep, preparing them for transfer to the neocortex.

How do we know? Uniform Manifold Approximation & Projection (UMAP) for dimension reduction is a tool that condenses 400-dimensional neural activity data into 3D for visualization. Mice navigating a maze showed hippocampal activity encoding location and learning progression; it also showed neural patterns reflecting maze layout and task mastery.

What this means in practical terms: you need to get good sleep if you don’t want to lose your memories!

    A Prescription For GLOVES

    Dr. Genma Newman is a Doctor with expertise in Plant Power.

    This is Dr. Gemma Newman. She’s a GP (General Practitioner, British equivalent to what is called a family doctor in America), and she realized that she was treating a lot of patients while nobody was actually getting better.

    So, she set out to help people actually get better… But how?

    The biggest thing

    The single biggest thing she recommends is a whole foods plant-based diet, as that’s a starting point for a lot of other things.

    Click here for an assortment of short videos by her and other health professionals on this topic!

    Specifically, she advocates to “love foods that love you back”, and make critical choices when deciding between ingredients.

    Click here to see her recipes and tips (this writer is going to try out some of these!)

    What’s this about GLOVES?

    We recently reviewed her book “Get Well, Stay Well: The Six Healing Health Habits You Need To Know”, and now we’re going to talk about those six things in more words than we had room for previously.

    They are six things that she says we should all try to get every day. It’s a lot simpler than a lot of checklists, and very worthwhile:

    Gratitude

    May seem like a wishy-washy one to start with, but there’s a lot of evidence for this making a big difference to health, largely on account of how it lowers stress and anxiety. See also:

    Love

    This is about social connections, mostly. We are evolved to be a social species, and while some of us want/need more or less social interaction than others, generally speaking we thrive best in a community, with all the social support that comes with that. See also:

    How To Beat Loneliness & Isolation

    Outside

    This is about fresh air and it’s about moving and it’s about seeing some green plants (and if available, blue sky), marvelling at the wonder of nature and benefiting in many ways. See also:

    Walking… Better.

    Vegetables

    We spoke earlier about the whole foods plant-based diet for which she advocates, so this is that. While reducing/skipping meat etc is absolutely a thing, the focus here is on diversity of vegetables; it is best to make a game of seeing how many different ones you can include in a week (not just the same three!). See also:

    Three Critical Kitchen Prescriptions

    Exercise

    At least 150 minutes moderate exercise per week, and some kind of resistance work. It can be calisthenics or something; it doesn’t have to be lifting weights if that’s not your thing! See also:

    Resistance Is Useful! (Especially As We Get Older)

    Sleep

    Quality and quantity. Yes, 7–9 hours, yes, regardless of age. Unless you’re a child or a bodybuilder, in which case make it nearer 12. But for most of us, 7–9. See also:

  • Unfuck Your Brain – by Dr. Faith Harper

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    This book takes a trauma-informed care approach, which is relatively novel in the mental health field and it’s quickly becoming the industry standard because of its effectiveness.

    The basic premise of trauma-informed care is that you had a bad experience (possibly even more than one—what a thought!) and that things that remind you of that will tend to prompt reactivity from you in a way that probably isn’t healthy. By identifying each part of that process, we can then interrupt it, much like we might with CBT (the main difference being that CBT, for all its effectiveness, tends to assume that the things that are bothering you are not true, while TIC acknowledges that they might well be, and that especially historically, they probably were).

    A word of warning: if something that triggers a trauma-based reactivity response in you is people swearing, then this book will either cure you by exposure therapy or leave you a nervous wreck, because it’s not just the title; Dr. Harper barely gets through a sentence without swearing. It’s a lot, even by this (European) reviewer’s standards (we’re a lot more relaxed about swearing over here, than people tend to be in America).

    On the other hand, something that Dr. Harper excels at is actually explaining stuff very well. So while it sometimes seems like she’s “trying too hard” style-wise in terms of being “not like other therapists”, in her defence she’s nevertheless a very good writer; she knows her stuff, and knows how to communicate it clearly.

    Bottom line: if you don’t mind a writer who swears more than 99% of soldiers, then this book is an excellent how-to guide for self-administered trauma-informed care.

  • I’ve been diagnosed with cancer. How do I tell my children?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    With around one in 50 adults diagnosed with cancer each year, many people are faced with the difficult task of sharing the news of their diagnosis with their loved ones. Parents with cancer may be most worried about telling their children.

    It’s best to give children factual and age-appropriate information, so children don’t create their own explanations or blame themselves. Over time, supportive family relationships and open communication help children adjust to their parent’s diagnosis and treatment.

    It’s natural to feel you don’t have the skills or knowledge to talk with your children about cancer. But preparing for the conversation can improve your confidence.

    Preparing for the conversation

    Choose a suitable time and location in a place where your children feel comfortable. Turn off distractions such as screens and phones.

    For teenagers, who can find face-to-face conversations confronting, think about talking while you are going for a walk.

    Consider if you will tell all children at once or separately. Will you be the only adult present, or will having another adult close to your child be helpful? Another adult might give your children a person they can talk to later, especially to answer questions they might be worried about asking you.

    Finally, plan what to do after the conversation, like doing an activity with them that they enjoy. Older children and teenagers might want some time alone to digest the news, but you can suggest things you know they like to do to relax.

    Also consider what you might need to support yourself.

    Preparing the words

    Parents might be worried about the best words or language to use to make sure the explanations are at a level their child understands. Make a plan for what you will say and take notes to stay on track.

    The toughest part is likely to be saying to your children that you have cancer. It can help to practise saying those words out aloud.

    Ask family and friends for their feedback on what you want to say. Make use of guides by the Cancer Council, which provide age-appropriate wording for explaining medical terms like “cancer”, “chemotherapy” and “tumour”.

    Having the conversation

    Being open, honest and factual is important. Consider the balance between being too vague, and providing too much information. The amount and type of information you give will be based on their age and previous experiences with illness.

    Remember, if things don’t go as planned, you can always try again later.

    Start by telling your children the news in a few short sentences, describing what you know about the diagnosis in language suitable for their age. Generally, this information will include the name of the cancer, the area of the body affected and what will be involved in treatment.

    Let them know what to expect in the coming weeks and months. Balance hope with reality. For example:

    The doctors will do everything they can to help me get well. But, it is going to be a long road and the treatments will make me quite sick.

    Check what your child knows about cancer. Young children may not know much about cancer, while primary school-aged children are starting to understand that it is a serious illness. Young children may worry about becoming unwell themselves, or other loved ones becoming sick.

    Older children and teenagers may have experiences with cancer through other family members, friends at school or social media.

    This process allows you to correct any misconceptions and provides opportunities for them to ask questions. Regardless of their level of knowledge, it is important to reassure them that the cancer is not their fault.

    Ask them if there is anything they want to know or say. Talk to them about what will stay the same as well as what may change. For example:

    You can still do gymnastics, but sometimes Kate’s mum will have to pick you up if I am having treatment.

    If you can’t answer their questions, be OK with saying “I’m not sure”, or “I will try to find out”.

    Finally, tell children you love them and offer them comfort.

    How might they respond?

    Be prepared for a range of different responses. Some might be distressed and cry, others might be angry, and some might not seem upset at all. This might be due to shock, or a sign they need time to process the news. It also might mean they are trying to be brave because they don’t want to upset you.

    Children’s reactions will change over time as they come to terms with the news and process the information. They might seem like they are happy and coping well, then be teary and clingy, or angry and irritable.

    Older children and teenagers may ask if they can tell their friends and family about what is happening. It may be useful to come together as a family to discuss how to inform friends and family.

    What’s next?

    Consider the conversation the first of many ongoing discussions. Let children know they can talk to you and ask questions.

    Resources might also help; for example, The Cancer Council’s app for children and teenagers and Redkite’s library of free books for families affected by cancer.

    If you or other adults involved in the children’s lives are concerned about how they are coping, speak to your GP or treating specialist about options for psychological support.

  • 5 Ways To Naturally Boost The “Ozempic Effect”

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Dr. Jason Fung is perhaps most well-known for his work in functional medicine for reversing diabetes, and he’s once again giving us sound advice about metabolic hormone-hacking with dietary tweaks:

    All about incretin

    As you may gather from the thumbnail, this video is about incretin, a hormone group (the most well-known of which is GLP-1, as in GLP-1 agonists like semaglutide drugs such as Ozempic, Wegovy, etc) that slows down stomach emptying, which means a gentler blood sugar curve and feeling fuller for longer. It also acts on the hypothalmus, controlling appetite via the brain too (signalling fullness and reducing hunger).

    Dr. Fung recommends 5 ways to increase incretin levels:

    • Enjoy dietary fat: healthy kinds, please (e.g. nuts, seeds, eggs, etc—not fried foods), but this increases incretin levels more than carbs
    • Enjoy protein: again, prompts higher incretin levels of promotes satiety
    • Enjoy fiber: this is more about slowing digestion, but when it’s fermented in the gut into short-chain fatty acids, those too increase incretin secretion
    • Enjoy bitter foods: these don’t actually affect incretin levels, but they can bind to incretin receptors, making the body “believe” that you got more incretin (think of it like a skeleton key that fits the lock that was designed to be opened by a different key)
    • Enjoy turmeric: for its curcumin content, which increases GLP-1 levels specifically

    For more information on each of these, here’s Dr. Fung himself:

  • Hardwiring Happiness – by Dr. Rick Hanson

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Publishers are very excitable about “the new science of…”, and it’s almost never actually a new science of. But what about in this case?

    No, it isn’t. It’s the very well established science of! And that’s a good thing, because it means this book is able to draw on quite a lot of research and established understanding of how neuroplasticity works, to leverage that and provide useful guidance.

    A particular strength of this book is that while it polarizes the idea that some people have “happy amygdalae” and some people have “sad amygdalae”, it acknowledges that it’s not just a fated disposition and is rather the result of the lives people have led… And then provides advice on upgrading from sad to happy, based on the assumption that the reader is quite possibly coming from a non-ideal starting point.

    The bookdoes an excellent job of straddling neuroscience and psychology, which sounds like not much of a straddle (the two are surely very connected, after all, right?) but this does mean that we’re hearing about the chemical structure of DNA inside the nuclei of the neurons of the insula, not long after reading an extended gardening metaphor about growth, choices, and vulnerabilities.

    Bottom line: if you’d like a guide to changing your brain for the better (happier) that’s not just “ask yourself: what if it goes well?” and similar CBTisms, then this is a fine book for you.

    Q: Why is your newsletter called 10almonds? Maybe I missed it in the intro email, but my curiosity wants to know the significance. Thanks!”

    It’s a reference to a viral Facebook hoax! There was a post going around that claimed:

    ❝HEADACHE REMEDY. Eat 10–12 almonds, the equivalent of two aspirins, next time you have a headache❞ ← not true!

    It made us think about how much health-related disinformation there was online… So, calling ourselves 10almonds was a bit of a tongue-in-cheek reference to that story… but also a reminder to ourselves:

    We must always publish information with good scientific evidence behind it!
