Furthermore, while depression and anxiety are frequently comorbid, dissociation of the two in animal models is difficult to achieve. [128] Pharmacological assessment of validity is frequently disconnected from clinical pharmacotherapeutics in that most screening tests assess acute effects, while antidepressants normally take a few weeks to work ...
Poor diet in early childhood affects the number of neurons in parts of the brain. [1]Nutritional neuroscience is the scientific discipline that studies the effects various components of the diet such as minerals, vitamins, protein, carbohydrates, fats, dietary supplements, synthetic hormones, and food additives have on neurochemistry, neurobiology, behavior, and cognition.
Each macronutrient can impact cognition through multiple mechanisms, including glucose and insulin metabolism, neurotransmitter actions, oxidative stress and inflammation, and the gut-brain axis. [ 4 ] [ 5 ] [ 6 ] Inadequate macronutrient consumption or proportion could impair optimal cognitive functioning and have long-term health implications.
In plants and animals, mineral absorption, also called mineral uptake is the way in which minerals enter the cellular material, typically following the same pathway as water. In plants, the entrance portal for mineral uptake is usually through the roots. Some mineral ions diffuse in-between the cells. In contrast to water, some minerals are ...
Inadequacy of the monoamine hypothesis of depression While depression is a complex condition with many factors involved, it is commonly attributed to an imbalance of several key monoamine neurotransmitters , including serotonin , dopamine and norepinephrine .
The forgetting curve hypothesizes the decline of memory retention in time. This curve shows how information is lost over time when there is no attempt to retain it. [1] A related concept is the strength of memory that refers to the durability that memory traces in the brain. The stronger the memory, the longer period of time that a person is ...
Thus, a damaged hippocampus can cause memory loss and inability of cognitive function. Furthermore, as the hippocampus is the region controlling learning and memory processes, the research on Schaffer collaterals may help to find treatments for diseases related to the hippocampus or its neural processing pathways such as Alzheimer's disease , a ...
Serotonin (/ ˌ s ɛr ə ˈ t oʊ n ɪ n, ˌ s ɪər ə-/) [6] [7] [8] or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter.Its biological function is complex, touching on diverse functions including mood, cognition, reward, learning, memory, and numerous physiological processes such as vomiting and vasoconstriction.
