Worksheet 1: Forebrain and Cerebral Cortex

Cerebral Cortex

Rostral region focuses on movement-related activities and caudal region focuses on perceiving and learning

Corpus Callosum

Connects R&L hemispheres and allows information to pass between them

Ventricles

Interconnected fluid-filled spaces that cushion and protect the brain, as well as wash out debris

Hippocampus

Early memory storage, formation of long-term memory, spatial recognition

Hypothalamus

Hunger, thirst, body temp, sexual activity, arousal, parenting, perspiration, BP, HR, shivering, pupil dilations, circadian rhythms, sleep

Amygdala

Fear-processing, emotion processing, learning, fight-or-flight response, reward processing

Cingulate Cortex

Pain processing, emotion, memory, self-regulation

Septum

Memory, emotion processing, separation of lateral ventricles

Olfactory Bulb

Sends olfactory information to the amygdala to be processed

Uncus

Olfactory sensations and emotional memory processing

Mammillary Bodies

Controlling emotional expressions, consolidating memories, spatial memory

Thalamus

Relay motor & sensory information, memory, alertness, consciousness, contributes to perception and cognition

Lateral Geniculate Nucleus

receives fibers from the retina and projects fibers to the primary visual cortex

Medial Geniculate Nucleus

receives fibers from the auditory system and projects fibers to primary auditory cortex

Pituitary gland

Hormone secretion, specifically oxytocin and vasopressin

Pineal body

regulate circadian rhythm by secreting melatonin
