Human Brain Anatomy and Function

The Human Brain

• The brain has a wrinkly surface with bumps and folds, allowing for a greater surface area, more neurons, and increased cellular mass.

Cerebral Cortex

• The cerebral cortex is the outer portion of the brain and can be divided into four hemispheres: frontal, parietal, occipital, and temporal lobes.

Frontal Lobe

• The frontal lobe is responsible for motor movements and executive functions such as thinking, problem-solving, and supervising other brain areas.
• The motor cortex or motor strip is a part of the frontal lobe, controlling body movements and allowing for electric stimulation to make specific body parts move.
• The prefrontal cortex is also part of the frontal lobe, responsible for executive functions, thinking, and problem-solving.
• Broca's area is a part of the frontal lobe, associated with speech production.

Parietal Lobe

• The parietal lobe is important for tasks such as spatial processing and manipulation, allowing for understanding of three-dimensional space.
• The somatosensory cortex is part of the parietal lobe, receiving information from the body about touch, pressure, temperature, and pain.
• The sensorimotor cortex is a combination of the motor cortex and somatosensory cortex, working together to enable movement and sensation.

Occipital Lobe

• The occipital lobe is responsible for vision processing, with information collected from the eyes transported to the back of the brain for processing.
• The striate cortex is a term used to describe the striped appearance of occipital lobe cells under a microscope.

Temporal Lobe

• The temporal lobe is responsible for auditory processing, with information collected from the ears transported to the brain for processing.
• Wernicke's area is a part of the temporal lobe, responsible for language reception and comprehension.

The Human Brain

• The brain's surface is wrinkly with bumps and folds, increasing its surface area, allowing for more neurons, and boosting cellular mass.

Cerebral Cortex

• The cerebral cortex is the outermost layer of the brain, divided into four main regions: frontal, parietal, occipital, and temporal lobes.

Frontal Lobe

• The frontal lobe oversees motor movements and executive functions, including thinking, problem-solving, and regulating other brain regions.
• The motor cortex, responsible for controlling body movements, is located in the frontal lobe and can be stimulated electrically to move specific body parts.
• The prefrontal cortex, also part of the frontal lobe, is responsible for executive functions, thinking, and problem-solving.
• Broca's area, a region in the frontal lobe, plays a key role in speech production.

Parietal Lobe

• The parietal lobe is essential for spatial processing and manipulation, enabling understanding of three-dimensional space.
• The somatosensory cortex, part of the parietal lobe, receives sensory information from the body about touch, pressure, temperature, and pain.
• The sensorimotor cortex, a combination of the motor cortex and somatosensory cortex, works together to facilitate movement and sensation.

Occipital Lobe

• The occipital lobe is dedicated to processing visual information, receiving data from the eyes and processing it at the back of the brain.
• The striate cortex, characterized by its striped appearance under a microscope, is a region within the occipital lobe.

Temporal Lobe

• The temporal lobe is responsible for processing auditory information, receiving data from the ears and processing it in the brain.
• Wernicke's area, located in the temporal lobe, is essential for language reception and comprehension.
