The Brain weighs 1300 - 1400 g made up of about 100 billion neurons “the most complex living structure on the universe” Society for Neuroscience makes us who we are
The Cerebrum: The cerebrum is the largest part of the human brain, associated with higher brain function such as thought & action. The cerebral cortex is divided into four sections, called "lobes": the frontal lobe, parietal lobe, occipital lobe, and temporal lobe.
What do each of these lobes do? Frontal Lobe- associated with reasoning, planning, parts of speech, movement, emotions, and problem solving Parietal Lobe- associated with movement, orientation, recognition, perception of stimuli Occipital Lobe- associated with visual processing Temporal Lobe- associated with perception and recognition of auditory stimuli, memory, and speech
The Cerebellum: The cerebellum, or "little brain", is similar to the cerebrum in that it has two hemispheres and has a highly folded surface or cortex. This structure is associated with regulation and coordination of movement, posture, and balance.
Brain Stem: This structure is responsible for basic vital life functions such as breathing,heartbeat, and blood pressure. The brain stem is made of the midbrain, pons, and medulla.
Midbrain: It is involved in functions such as vision, hearing, eye movement, and body movement. Also important for voluntary motor function
Pons: part of the hindbrain It is involved in motor control and sensory analysis... for example, information from the ear first enters the brain in the pons. It has parts that are important for the level of consciousness and for sleep. Some structures within the pons are linked to the cerebellum, thus are involved in movement and posture.
Medulla Oblongata: this structure is between the pons and spinal cord. It is responsible for maintaining vital body functions, such as breathing & heart rate
Hypothalamus: Autonomic Function Control (heart rate, digestion, sex drives) Endocrine Function Control Homeostasis Motor Function Control Food & Water Intake Regulation Sleep-Wake Cycle Regulation
Thalamus: processes and relays movement and sensory information It is essentially a relay station, taking in sensory information and then passing it on to the cerebral cortex The cerebral cortex also sends information to the thalamus, which then sends this information to other systems.
