What is the forebrain responsible for?
Higher cognitive functions such as thinking, processing information, making decisions, sensory processing involved in planning and executing movements, behavioral responses, sleep-wake cycles by producing melatonin, controlling body temperature, reproductive functions, eating, and display of emotion.
What does the midbrain connect?
It connects the forebrain, midbrain, and the cerebrum to the pons.
What is the midbrain responsible for?
Auditory and visual reflexes, controlling body movement (especially eye movement), managing sleep-wake cycles, and temperature regulation.
What does the hindbrain regulate?
Vital functions that are essential for survival such as breathing, heart rate, sleep and wakefulness, coordinating motor activity and balance.
What structures make up the hindbrain?
medulla, pons, and cerebellum
What is the cerebellum responsible for?
motor control, coordination, balance, posture, processing sensory feedback from the eyes and inner ears to process nerve impulses and coordinate muscle movement.
What does the brainstem control?
breathing, heart rate, blood pressure, coughing, and sneezing
What are the four lobes of the brain?
Frontal, Parietal, Temporal, and Occipital
What is the frontal lobe involved in?
reasoning, motor control, emotion, language
What structures does the frontal lobe contain?
Motor cortex, prefrontal cortex, and Broca’s area
What does the motor cortex do?
plans and coordinates movement
What does the prefrontal cortex do?
It is responsible for higher-cognitive functioning
What does Broca’s area do?
It is essential for language production.
What is the parietal lobe involved in?
Processing information from the body’s senses
What structure does the parietal lobe contain?
Somatosensory cortex
What does the Somatosensory cortex do?
It is essential for processing sensory information from across the body.
What is the temporal lobe associated with?
hearing, memory, emotion, and some aspects of hearing
What structure does the temporal lobe contain?
Auditory cortex, wernicke’s area
What does the auditory cortex do?
main area for processing auditory information
What does wernicke’s area do?
important for speech comprehension
What is the occipital lobe responsible for?
interpreting visual information
What structure does the occipital lobe contain?
primary visual cortex
What does the primary visual cortex do?
organized retinotopically, meaning there is a close relationship between the position of an object and in a person’s visual field and the position of that object’s representation on the cortex.
What is the limbic system involved in?
processing emotion and memory
What does the limbic system contain?
hypothalamus, amygdala, and hippocampus
Where is the reticular formation?
It extends from the forebrain down to the hindbrain and is centered in the midbrain.
What does the reticular formation regulate?
sleep-wake cycle, arousal, alertness, motor activity
What is a synapse?
A synapse is a junction between two nerve cells consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter.
What is a terminal button?
A terminal button is an axon terminal containing synaptic vesicles that release chemicals called neurotransmitters.
What is the longitudinal fissure?
It is a deep grove in the brain’s cortex that separates the two brain hemispheres.
