Document Summary
Types of synapses: electrical, mediated by connexions. Involved direct transmission between cytosol of different molecules: fast transmission, synchronizes electrical activity among neurons, chemical/synaptic. Biogenic amine neurotransmitters: dopamine, norepinephrine (noadrenaline) catecholamines, epinephrine (adrenaline, histamine, serotonin. Ex: of when we move way from the balance of concentration or amount, there are bad effects. Implicated in sleep regulation as well: dopamine inhibits norepinephrine"s release and stimulation of the pineal gland (to release melatonin) Serotonin: depression serotonin is a mood balancer; a deficit can lead to depression. Neural circuits: affected by environment and genetics. 5 hours later, the motor area of brain activated, when you listen to piano music. Frontal association cortex mediates planning and decision making: responsible for logical reasoning, planning, etc, cognitive tasks can evaluate frontal lobe functioning; like the wisconsin card. Sorting task makes comments about planning ability, the delayed response task evaluates memories, and the nogo task, which evaluates inhibition.
