Cerebellum
Muscle Tone, Balance, and Finely
Coordinated Movement
Occipital Lobe
Area V1
Primary Motor Cortex
Medial Longitudinal Fissure
Divides the brain into two equal
hemispheres.
What are the basic functions of each
of the four cerebral lobes?
Frontal – Cognition, Planning,
Motor Control
Parietal – Somatosensory input,
Proprioception, Language
Temporal – Memory, Emotion,
Audition, Sexual & Social
Behaviour
Occipital - Vision
Pons
Connect the Medulla to the Midbrain
and Thalamus. Contains numerous
tracts including the Cortico-spinal
tracts and Reticular Formation
Olfactory Tract
Relay olfactory impulses from the
olfactory bulbs to the entorhinal
cortex
Cerebral Peduncles
Contain descending fibres of the
Corticospinal Tracts
Receives afferents from sensory
modalities and relay via
Thalamus
Mammillary Bodies
Sexual Arousal
Memory
Emotion
Trapezoid Bodies
Sound localization via interneurons
that inhibit ipsilateral signals and
amplify contralateral signals to
increase amplitude and temporal
differences
Corpus Callosum
Relay signals between the two
hemispheres
Pineal Body
Endocrine functions: secretes
melatonin, controls daily rhythms
In vertebrates other than humans:
secretes hormones affecting
reproductive behaviour
Inferior Colliculus
Intermediate nucleus for
processing auditory signals
before they are transmitted to the
primary auditory cortex
Cingulate Gyrus
Pain perception, Visceral
Responses to Emotion, and
Planning of Motor Action
Anterior Commisure
Globus Pallidus
Posture, Muscle tone, and control of
Eating and Drinking
Column of the Fornix
Memory and Control of Eating
Hippocampus
Emotion, motivation, navigation
by cognitive maps, learning, and
the consolidation of long-term
memory
Head of the Caudate Nucleus
Inhibitory Control of Movement
Periaqueductal Gray
Contains opiate neuroreceptors and
neurons that release endorphins
Implicated in the sensation and
suppression of pain
Implicated in the control of
aggression and in female sexual
behaviour.
Internal Capsules
Nerve fibres running from the
thalamus to the left or right
cerebral cortex and from the
cerebral cortex to the thalamus,
brainstem, and spinal cord
Superior Colliculus
Processes spatial aspects of visual info
Directs eye movement in the direction
of visual attention
Optic Tract
Relays amalgamated visual
information from the Optic
Chiasm to the LGN
Putamen
Posture and Movement Control
Claustrum
Anterior: Cortical Pain Centre
Posterior: Language
