Sources
Frontal Lobe

Location
: Portion of the cerebral cortex lying just behind the forehead
Function
: The Frontal Lobe is involved in speaking and muscle movements. Also responsible for making plans and judgments
Other
: The
Motor Cortex
controls voluntary movement. It is located at the rear of the Frontal Lobe. The
Broca's Area
controls languge expression and directs the muscle movements involved in speech. Found in the left frontal lobe.
Parietal Lobe
Temporal Lobe
Location
: Lies roughly above the ears
Function
: Auditory information is processed through this part of the cerebral cortex
Other
: The
Wernicke's Area
controls language reception, found in the left temporal lobe.
Occipital Lobe
The Forebrain
The Midbrain
The Hindbrain
Each Cerebral Hemisphere is divided into sections or lobes, each of which specializes in different function.
Largest part of the brain.
Made up of the thalamus, the hypothalamus, and the limbic system.
Thalamus
- Located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla.
Hypothalamus
- Lying below the thalamus; it directs several maintenance activities (eating, drinking, body temperature), helps govern the endocrine system via the pituitary glands, and is linked to emotion and reward.
The limbic system
- A Doughnut-shaped neural system (including the hippocampus, amygdala, and hypothalamus) located below the cerebral hemispheres; associated with emotions and control.
The Midbrain is a portion of the central nervous system, which is associated with vision, hearing, motor control, sleep/wake, arousal (alertness), and temperature regulation.
Limbic System
Amygdala
- neural clusters in the limbic system; linked to emotion.
Hippocampus
- attaches memories to the emotions and senses that went with them.
Includes the upper part of the spinal cord, the brain stem, and the cerebellum.
Controls the body’s vital functions such as respiration and heart rate.
Cerebellum
- coordinates movement and is involved in learned involuntary movements.
Spinal Cord
- the main pathway for information connecting the brain and peripheral nervous system.(sensory and motor neurons that connect the central nervous system to the rest of the body. )
Brain stem
- The oldest part and central core of the brain, beginning where the spinal cord swells as it enters the skull; the brainstem is responsible for automatic survival functions.
Most of the actual information processing in the brain takes place in the cerebral cortex.
The cortex is gray because nerves in this area lack the insulation that makes most other parts of the brain appear to be white.
The folds in the brain add to its surface area and therefore increase the amount of gray matter and the quantity of information that can be processed.
The inner brain is the gate-keeper between the spinal cord and the cerebral hemispheres.
The function of the inner brain is to determine our emotional state, modify our perceptions and responses plus it allow us to initiate movements that you make without thinking about them.

Structures:
Hypothamalus
- I
mportant emotional center(makes you feel happy or sad)
Thamalus
- C
ollects and distributes infromation going to and from the spinal cord and the cerebrum
Hippocampus
-M
emory indexer(sends memories out and retrieves them when neccesary)
Basal Ganglia
- R
esponsible for initiating and unify movements(voluntary motor control)
Location
: Portion of the cerebral cortex lying at the back of the head.
Function
: The Occipital Lobe receives information from the visual fields and processes it.
Other
: The Occipital Lobe includes the
Visual Cortex
, that receives and processes sensory nerve impulses from the eyes.
Location
: Portion of the cerebral cortex lying at the top of the head and toward the rear.
Function
: Receives sensory input for touch and body position.
Other
: The front of the parietal lobe includes the
sensory cortex
, which registers and processes body touch and movement sensations.
