Neuroscience

Question 1

Axon

Answer 1

fibers that project from body of neuron and split into dendrites

Question 2

Myelination

Answer 2

myelin sheaths that protect axon fibers and aids in propagating electrical impulses along axon

Question 3

Cerebral Cortex

Answer 3

brain divided into two hemispheres covered with grey matter. all parts are interacting and interconnected, key roles in memory, thought, language, perception, emotion and consciousness

Question 4

Frontal Lobe

Answer 4

Planning, movement, memory, social judgement and abstract thinking

damage to frontal: difficulties interpreting feedback from environment (lack of social judgement), changes in social +sexual behaviors

Question 5

Temporal Lobes

Answer 5

process auditory information, influence in emotion

damage: memory problems, fails to display emotion, react appropriately to dangerous situations

Question 6

Parietal lobe

Answer 6

Controls language comprehension, spatial orientation, perception, sense of touch
damage: apraxia( inability to preform an action ) agnosia(inability to recognize)

Question 7

Occipital Lobe

Answer 7

Vision and visual associations

damage: loss of visual awareness, visual hallucinations, illusions

Question 8

limbic system

Answer 8

emotion center of the brain

memory- trauma

Question 9

Neurons

Answer 9

Brain cells that receive, process and transmit information.

Communication through neurotransmitters

Question 10

Amygdala

Answer 10

emotion and memory

trauma: amygdala over-activated affects cognitive structure leading to cognitive distortions

Question 11

Neuroplasticity

Answer 11

neurons that fire together wire together- social environmental and interpersonal interactions influence fire together

Question 12

Neuroscience Pros

Answer 12

applications in both micro (bio-psycho-social) and macro practice (psychopharm and psychotropic meds)understanding of human behaviors and practice
amygdala and trauma
fight, flight, freeze response
Neuroplasticity- neurons that fire and wire together
mental health issues have chemical etiology
explanations of sympathetic and parasympathetic nervous system and activities that may enhance relaxation response
theories inherent in neuropsych-useful for variety of psychological issues: memory, sleep, attention, schizophrenia, alzheimer disorders

Question 13

neuroscience cons

Answer 13

Attribution of deviant behavior to brain functions
minimizes environmental long term stressors
its a combination of meds, therapies and counseling=sustained progress
DSM IV TR- heavily weighted in disorders having biological etiology-justifies psychotropic drugs
medications not successful with personality disorders- borderline need psychotherapy; antisocial not responsive to psychotherapy
Not easily accessible
faulty assumptions that may lead to false diagnosis
Neuroplasticity-reactions to trauma are different
Diagnosis in biological harder to remove- leading to unsuccessful treatment
