,• Maintains focused attention
• Registers acts of aggression
• Wernicke's area located in the left temporoparietal junction is responsible for the
comprehension of speech??
Temporal lobe - ANSWER • Emotion and memory circuits
• Hearing, learning, memory circuits, sexual identity, and processing of auditory
stimuli

Cerebrum - ANSWER • Functions as an auxiliary structure for the entire cerebral
cortex
• Posture and balance in walking
• Sequential movements required in eating and writing
• Control speed and acceleration of movement
• Involved in smooth eye movement
• Cognition and language
• Memory and impulse control
Brainstem (Medulla oblongata, pons, and midbrain) - ANSWER • Medulla oblongata-
regulation of blood pressure, respiration, and digestion. Reflex center for vomiting
coughing, sneezing, swallowing, and hiccupping.
• Pons- Relays information from the cerebral hemisphere to the cerebellum
• Midbrain- control many sensory and motor functions including eye movement
Locus ceruleus - ANSWER • Produces norepinephrine
• Activity maintains arousal

Dorsal raphe - ANSWER • Produces serotonin
• Control sleep wake cycle
Reticular activating system (RAS) - ANSWER • Involved in arousal and sleep- the
"toggle switch"
• Switches the cerebral cortex on when individual is relaxed

• Regulates thalamus and cortex activities that are involved in emotions
• Involved in processing pain and in regulation of heartrate, breathing, perspiration,
swallowing, coughing, salivation, urination, and sexual arousal
Reticular activating system (RAS) - ANSWER • Involved in arousal and sleep- the
"toggle switch"
• Switches the cerebral cortex on when individual is relaxed
, • Switches limbic system on when there is a threat
• Regulates thalamus and cortex activities that are involved in emotions

swallowing, coughing, salivation, urination, and sexual arousal
Hypothalamus - ANSWER • Bridges internal homeostasis and outside environment

• Regulates the autonomic nervous system and secretion of pituitary hormones
• Involved in hunger, thirst, water balance, regulation of temperature, circadian
rhythms, and stress response
Thalamus - ANSWER • Gaits information to the neocortex
• Processes information coming from the 5 senses and information coming from the
