Biological Basis Flashcards
Made up of brain and spinal cord
Central Nervous System
The rest of the nervous system, e.g. not brain or spinal cord
Peripheral Nervous System
Somatic Nervous System
Voluntary Movement
Autonomic Nervous System
Involuntary movement of muscle
Arouses the body for fight or flight
Sympathetic Nervous System
Parasympathetic Nervous System
establishes homeostasis after a sympathetic response (inhibitory)
Chemicals released in the synaptic gap and received by neurons
Neurotransmitters
Major inhibitory neurotransmitter
GABA
major Excitatory neurotransmitter
glutamatE
Neurotransmitter that effect internal reward system and movement
Dopamine
Neurotransmitter that effects moods and emotions
Serotonin
Hormone effecting memory
Acetylcholine
Hormones involved in sympathetic nervous system arousal
Epinephrine and Norepinephrine
Effect pain control and happiness
Endorphins
Hormone related to love and bonding (also uterine contractions)
Oxytocin
Drugs that mimic a neurotransmitter
Agonist
Drug that blocks a neurotransmitter
Antagonist
when unused neurotransmitters are taken back up into the sending neuron; SSRIs block this
Reuptake
Oldest part of the brain
Hindbrain
Part of brain involved with movement
Cerebellum
Part of brain that controls vital organs, e.g. the heart
Medulla Oblongata
Part of the brain involved with sleep/arousal
Pons
Part of the brain concerned with the attention span
Reticular Formation
Region of the brain concerned with higher thought process
Forebrain
Part of the brain responsible for fear and emotions
Amygdala
Part of the brain responsible for memory
Hippocampus
Relay center of the brain
Thalamus
Part of the brain referred to as the pleasure center and concerned with eating behaviors
Hypothalamus
The area of the brain concerned with speech
Broca’s Area
the area of the brain concerning comprehension of speech
Wernicke’s Area
Outer region of the brain
Cerebral Cortex
Located in the back of the head; concerned with vision
Occipital Lobe
Part of brain concerned with decision making, planning, judgement, movement, personality
Frontal Lobe
Located on top of the head and responsible for processing sensations (sensory input)
Parietal Lobe
Located on the sides of the head; related to hearing and face recognition
Temporal Lobe
map of sensory receptors, in parietal lobe
Somatosensory cortex
Map of our motor receptors, in frontal lobe
Motor cortex
Bundle of nerves that connect the 2 hemispheres of the brain; sometimes severed in patients with severe seizures
Corpus Callosum
the belief that functions are preformed in specific regions of the brain
Lateralization
Completed by Sperry & Gazzanaga; images shown to the right hemisphere will be processed in the left
Split-brain experiments
The brain’s ability to heal itself
Brain Plasticity
Identical Twins are referred to as:
Monozygotic
Fraternal twins are referred to as:
Dizygotic
Genetically, these twins have a higher chance of developing a disorder if the other has it
Monozygotic
