What neurological disease is this?

Amygdala, explicit

differentiate sprouting and pruning.
Sprouting - growth of dendrites during learning
Pruning- death of synapses due o disuse of neurons
Explain the role of pineal gland and hormone melatonin in sleep. What happens when it get dark? What happens when there is light?
Pineal gland is a small brain structure that produces and releases melatonin. When it gets dark, the pineal gland releases more melatonin, which makes us feel sleepy. When it is light, melatonin levels decrease, which helps us feel more awake.
Any variable, other than the IV, that can cause a change in the DV and therefore affect the result of an experiment in an unwanted way. An ________ may become a __________.
Extraneous Variables, Confounding Variables.
Self-fulfilling prophecy
________ plays a role in memory and learning and is the most common type of neurotransmitter in the __________.
Glutamate, central nervous system.
Not able to create any new memory, both semantic and episodic.
validity - refers to the extent to which an assessment tool actually measures what it is designed to measure.

how do neurohormones differ from neurotransmitters?
also, give 2 examples to each.
Neurotransmitters do not travel through the bloodstream, while hormones can travel quite some distance in the bloodstream. Neurohormones are those neurotransmitters that are able to act as both neurotransmitters and hormones.
Neurotransmitter - glutamate, aspartate, acetylcholine, GABA.
Neurohormone - serotonin, endorphines, dopamine.
We are more likely to remember events that produce strong emotional reactions than events that do not. Why?
This is partly attributable to the increased amount of adrenaline and noradrenaline in the amygdala during times of heightened emotional arousal, which signals our hippocampus to strengthen the consolidation of long-term memory.
The researcher should avoid continually imposing on the same people to participate in their investigation when other suitable participants are available. What is the ethic in psychological research that is involved here?
Justice
