Chapter 2 Brain Parts Flashcards
hormone produced by the adrenal glands that is released into the bloodstream in response to stress
epinephrine
regulatory system of the brain that influences a person’s response to stress and ability to regulate emotions
hypothalamic–pituitary–adrenal (HPA) axis
Enable self-control, judgment, emotional regulation; restructured in teen years.
Frontal lobes
Enables intelligence, consciousness, and self-awareness; reaches full maturity in 20s
Corpus callosum
Integrate auditory, visual, and tactile signals; immature until age 16
Parietal lobes
Influence emotional maturity; still developing after age 16
Temporal lobes:
Which areas comprise the human brain?
Brain stem, hindbrain , midbrain, and forebrain
Brain circuits and _______________ relate to particular psychological disorders, permitting more targeted treatments. Psychoactive drugs work by either increasing or decreasing their flow.
Neurotransmitters
Important for forming new memories and long-term memory. Important to stress reactivity
Hippocampus
Governs stress and fear response. Stimulation produces behavioural arousal and even rage reactions. Atrophy/damage can cause inability to recognize fearful expressions or situation.
Amygdala
(master regulator) maintains constant internal state. Regulates body temperature, hunger, thirst, fatigue, anger, and circadian cycles. Releases hormones into pituitary gland.
Hypothalamus
The hypothalamus control centre, coupled with pituitary and adrenal glands, make up this regulatory system in the brain
hypothalamic–pituitary–adrenal (HPA) axis
Similar to biochemical currents in the brain. These currents develop in an organized fashion to make meaningful connections that serve larger functions such as thinking and feeling.
Neurotransmitters
The hypothalamus secretes ____. The pituitary gland secretes ____. Adrenal Glands release the stress hormone ____
Corticotropin-hormone CRH Adrenocorticotropic hormone (ACTH) Cortisol
Neurotransmitter that governs motor coordination, inhibits exploration of surroundings, and regulates critical behaviour like eating, sleeping, and the expression of anger.
Serotonin.
