Empathy is a complex process, which involves at least two paths: “bottom-up” and “top-down”. The path “bottom-up”…

    The stress response

    The two main biological systems involved in stress response, ie. the sympathetic system and the hypothalamic-pituitary-adrenal axis (HPA), I described in the article Biology of stress. Now a little bit more about corticoliberin, as well as the locus coeruleus in the brainstem, dopaminergic and serotonergic system and the amygdala, hippocampus and prefrontal cortex. Corticoliberin (Corticotropin-releasing hormone…

    What you will not learn about the nervous system at school

    The article presents facts about the functioning of the nervous system, according to the latest research, but not necessarily consistent with the information from textbooks. Only neurons generate the action potential – False According to the textbook knowledge, neurons’ function is to transmit information in the form of electrical stimuli (action potential), and function of…

    Skydiving prevents depression?

    French scientists based on skydivers research published in 1999, found that sensation seeking can be an adaptive response to anhedonia, ie. an inability to experience pleasure. The creator of the theory of sensation seeking stated that the physiological basis of sensation seeking is the optimal level of arousal – in patients that achieve high scores in this scale…

    Time perception during tandem skydive

    The stories of people who during traumatic events seemed that time slowed down or stopped are well known. There are not many scientific studies that investigate the issue, but several scientists investigated this phenomenon in the lab.

    Endorphins

    Endorphins are opioid peptides, were identified in 1975 and their name comes from the words “Endogenous morphine,” that is produced in the body morphine. Due to the induced state of euphoric endorphins are often called “hormone of happiness”. There are a lot of molecules belonging to the group of endorphins; the most researched is beta-endorphin.

    Neurobiology of trust

    The main role in trust plays oxytocin – a neurotransmitter and a hormone that also has an impact on stimulating the secretion of milk and starting labor. The role of oxytocin examined Paul J. Zak – professor of economics and clinical neurology, who after examining animal studies found that this molecule may play a role in…

    The role of white matter in learning and mental illnesses

    The nervous system consists of gray matter and white matter. Grey matter is found mainly in the cortex, and is composed of the cell bodies of neurons (“gray cells”). White matter is nerve cell bodies projections (axons), which transmit information from the cell bodies to synapses connecting the neurons to each other. The majority of axons are…
