Hemispheres of the Brain

The Brain and the Spinal Cord

Spinal Cord Part of the central

nervous system.

Bundle of nerves that passes through the bones of the vertebrae down the back.

Sends sensations to the brain from the body, and returns motor commands to the various parts of the body.

primary role in reflexes and in the autonomic nervous system

Lobes of the Brain

Frontal Lobe

Temporal Lobe

Parietal Lobe

Occipital Lobe

Lobes of the Brain Description

Frontal Lobe Portion of cerebral cortex lying just behind the forehead

Involved in speaking and muscle movements and in making plans and judgments

Parietal Lobe Portion of cerebral cortex lying at the top of the head and towards the rear

Receives sensory input for touch and body positions

Its association areas work with the sensory signals or accurate perception

Temporal Lobe Portion of cerebral cortex lying roughly above the ears; includes auditory areas,

each receiving info primarily from opposite ear; controls hearing

Occipital Lobe Portion of cerebral cortex lying at the back of the head; Includes areas that

receive info from visual fields

Controls vision; contains visual cortex

Motor cortex an area at the rear of the frontal lobes that controls voluntary movements

Sensory Cortex area at the front of the parietal lobes that registers and processes body touch

and movement sensations

Visual cortex Area in the occipital lobe that receives input from eyes

Broca’s Area one of the main areas of the cerebral cortex responsible for speech production

Wernicke’s Area responsible for the comprehension of speech

Brain Stem

Pituitary Gland

Hypothalamus

Thalamus

Corpus Callosum

Cerebellum

Cerebral Cortex

Thalamus: Directs messages to sensory receiving areas in cortex and transmits replies to

cerebellum and medulla

Structure through which all sensory info (except smell) must pass through to get to cerebral cortex

Brainstem responsible for automatic survival functions

Cerebellum Helps coordinate movement; tells brain what to expect from body’s own

movement

Functions include processing sensory input and coordinating movement output and balance

Enables 1 type of nonverbal learning and memory; helps us judge time, modulate our emotions, and discriminate sounds and textures

Hypothalamus Directs several maintenance activities (i.e. sexual behavior, eating, drinking,

body temperature), helps govern endocrine system via pituitary gland, and is linked to emotion and reward

Pituitary Gland "Master Gland" because it secretes hormones and directs other organs and

endocrine glands, such as the adrenal glands, to suppress or induce hormone production.

Cerebral Cortex intricate fabric of interconnected neural cells covering the cerebral hemispheres

Body’s ultimate control and information processing center

Deeply convoluted over surface (“bark” of cerebrum most strongly linked to intelligence)

Corpus Callosum Divides the cerebrum into left and right hemispheres

Connects the left and right sides of the brain allowing for communication between both hemispheres

Transfers motor, sensory, and cognitive information between the brain hemispheres

Thalamus

Reticular Formation

Pons

Medulla

BRAINSTEM

Cerebellum

Parts of the Brainstem

Reticular Formation plays a role in regulation of sleep, arousal, and dreaming

Pons part of brainstem that acts as the “bridge” between brain stem and cerebellum

involved with sleep, arousal, and coordination of movements

Medulla base of brainstem, attached to spinal cord

controls unconscious but vital functions (i.e. breathing and heartbeat)

Amygdala Hippocampus

Amygdala 2 lima bean sized neural

clusters in limbic system linked to emotion (i.e. fear, aggression) that works with frontal lobe to regulate emotional responses

Hippocampus Processes memories
