Lobes of the Brain - Frontal

•The Frontal Lobe of the brain is located deep to the Frontal Bone

of the skull.

•It plays an integral role in the following functions/actions:

- Memory Formation

- Emotions

- Decision Making/Reasoning

- Personality

Lobes of the Brain - Parietal

•

The Parietal Lobe of the brain is located deep to theParietal Bone of the skull.

• It plays a major role in the following functions/actions:

- Senses and integrates sensation(s)

- Spatial awareness and perception(Proprioception - Awareness of body/ body parts in space and inrelation to each other)

Parietal Lobe - Cortical Regions

• Primary Somatosensory Cortex (Postcentral Gyrus)  –  Site involvedwith processing of tactile and proprioceptive information (a sensory

receptor, found chiefly in muscles, tendons, joints, and the inner ear

• Somatosensory Association Cortex - Assists with theintegration and interpretation of sensations relative to bodyposition and orientation in space. May assist with visuo-motorcoordination. 

• Primary Gustatory Cortex – Primary site involved with theinterpretation of the sensation of Taste.

Lobes of the Brain  –  Occipital

• The Occipital Lobe of the Brain

is located deep to the Occipital

Bone of the Skull.

•  Its primary function is the

processing, integration,

interpretation, etc. of VISIONand visual stimuli.

Occipital Lobe  –  Cortical Regions

• Primary Visual Cortex  –  This is the primary

area of the brain responsible for sight -

recognition of size, color, light, motion,

dimensions, etc.

• Visual Association Area  – Interprets

information acquired through the primaryvisual cortex.

Lobes of the Brain  –  Temporal

• The Temporal Lobes are located on the sides of the brain, deep

to the Temporal Bones of the skull.

• They play an integral role in

the following functions:

- Hearing

- Organization/Comprehension of language

- Information Retrieval(Memory and Memory Formation)

Temporal Lobe  –  Cortical Regions

•Primary Auditory Cortex

 – Responsible for hearing

•  Primary Olfactory Cortex  – Interprets the

sense of smell once it reaches the cortex via theolfactory bulbs. (Not visible on the superficial cortex)

• Wernicke’s Area  – Language comprehension.

Located on theL ef t 

Temporal Lobe.

• Frontal – voluntary motor functions

 – planning, mood, smell and social judgement

• Parietal – receives and integrates sensory information

• Occipital 

 – visual center of brain

• Temporal 

 – areas for hearing, smell, learning, memory, emotional

behavior
