Brain structure and function activity: Your task is to determine the functions of the following brain structures, and determine an example of the use of each of the structures in your own life and fill in the chart below. An example using driving has been provided. Brain structure Brain structure functions Provided Example: Driving functions My example: Cerebellum The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity. Coordinates hand movements on the steering wheel as well as pressing on the accelerator and brake pad Alcohol Reticular formation Sleep and consciousness – The reticular formation has projections to the thalamus and cerebral cortex that allow it to exert some control over which sensory signals reach the cerebrum and come to our conscious attention. It plays a central role in states of consciousness like alertness and sleep. Regulates our alertness or drowsiness while on the road Hot air balloon Corpus callosum Corpus callosum/the corpus callosum consists of about 200 millon axons that interconnect the two hemispheres. The primary function of the corpus callosum is to integrate motor, sensory, and cognitive performances between the cerebral cortex on one side of the brain to the same region on the other side. Shares sensory and motor driving information between hemispheres for a coordinated response to avoid an accident Girl with half a brain Brain stem Medulla The medulla oblongata helps regulate breathing, heart and blood vessel function, digestion, sneezing, and swallowing. This part of the brain is a center for respiration and circulation. Sensory and motor neurons (nerve cells) from the forebrain and midbrain travel through the medulla. Regulates breathing and heart rate; keeps your heart rate and respiratory rate just above coma level when driving across nebraska. https://www.youtube.com/watch?v=cu7A8LIzL1o Pons It is a bridge between various parts of the nervous system, including the cerebellum Sets breathing rate; Increases breathing rate and cerebrum when slamming on the brakes to avoid hitting a deer. Midbrain  A portion of the central nervous system associated with vision, hearing, motor control, sleep/wake, arousal (alertness), and temperature regulation. Conducts visual and auditory information messages to the thalamus and conducts motor information to the body’s muscles https://www.youtube.com/wat ch? v=WMlVNFpzKNI Diencephalon Thalamus The main function of the thalamus is to relay motor and sensory signals to the cerebral cortex. Relays the visual and auditory messages of the lights and sirens of a police car behind you to your cerebral cortex Hypothalamus One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland. Makes us aware of being warm or cold (to adjust temperature controls); to stop for food or drink because you are hungry and thirsty Limbic system Amygdala Shown to play a key role in the processing of emotions, the amygdala forms part of the limbic system. Activates during road rage Hippocampus The hippocampus is associated mainly with memory, in particular long-term memory.  Brings up memories of previous trips to grandma’s house so you remember where to turn Cerebral cortex Frontal lobe Involved in planning, organizing, problem solving, selective attention, personality and a variety of "higher cognitive functions" including behavior and emotions. Problem solving - do you pull over for the police or do you make a run for it? Grey’s Anatomy Season 4 Episode 12 Motor cortex The role of the primary motor cortex is to generate neural impulses that control the execution of movement. Initiates driving actions - moves the right foot to the gas or brake pedals Broca’s area Broca's area is responsible for producing language. It controls motor functions involved with speech Initiates the motor functions to sing with you passengers to your favorite jam. https://www.youtube.com/watch?v=DNpst50Zb98
