The majority of people who recovered from coma did not report any experiences that occurred while they were in coma (clinically unresponsive, with absent or minimal brainstem reflexes, and with severely abnormal EEG). However, some people who had cardiac arrest or came very close to clinical death but were successfully revived reported later that they had ...

Predicting individual side effects is generally not feasible in current clinical practice, although in the purview of "personalized medicine", mostly as a research goal/topic. For psychotropic medications, this is largely envisaged to work through pharmacogenomics:
In pharmacogenomics, genomic information is used to study individual responses to drugs. ...

Therapeutic effects and adverse reactions of psychoneuro-pharmaceutical drugs are tested using the same gold standard as usd for more conventional drugs, namely in randomized controlled trials.
Phase I trials focus on side effects and dosages in a small group of healthy subjects.
Phase II testings assess efficacy and side effects in a medium-sized ...

How can we earnestly predict the effects, both therapeutic and adverse, of psychotropic drugs on the specific patient in front of us?
The basic answer is that you cannot necessarily predict accurately how any medication will affect any individual person.
Medications can in general, carry risks of side effects. The risk levels of each side effect will also ...

I guess the answer depends on what you mean with "connected more than once".
Initially, being connected is a strictly binary relation: either two neurons are connected or not. (The question may be: directly or not. Indirectly, each pair of neurons is connected, as I assume.)
If you consider "being connected more or less strongly" - which is not a binary ...

As discussed previously in this thread, information (specifically, information that exists in the neural circuits), is probably the physical quantity that correlates perfectly with consciousness and, I would like to add, qualia. This is because information can have the same complexity, dynamicity, and content as consciousness and qualia do.
Now, what is the ...

In anatomy/physiology, there are 2 major categorizations of the nervous system:
Central nervous system (brain + spinal cord) and peripheral nervous system (all other neural structures)
Somatic nervous system, which controls skeletal muscles and skin, and and autonomic n. system, which controls internal organs, blood vessels and glands and is further divided ...

Simply put, pleasant/unpleasant sensations are associated with the activation of certain brain regions:
Many affective stimuli are hedonically complex mixtures containing
both pleasant and unpleasant components. To investigate whether the
brain represents the overall affective value of such complex stimuli,
or the affective value of the different ...

That one looks a bit familiar to me!
Short, simple answer
(extracted from the longer answer below...)
Measures of functional connectivity are just correlations (correlation here referring broadly to statistical relationships, not a specific statistic): they do not say anything about the causes of those correlations including whether they are direct or ...

Wikipedia has a comprehensive list of neurotransmitters, categorized as (a short list):
Amino acids: glutamate, aspartate, D-serine, γ-aminobutyric acid (GABA), glycine
Gasotransmitters: nitric oxide (NO), carbon monoxide (CO), hydrogen sulfide (H2S)
Monoamines: dopamine (DA), norepinephrine (noradrenaline; NE, NA), epinephrine (adrenaline), histamine, ...
