It is the largest lobe of the cerebral cortex. It is responsible for many behavioral traits, which include personality, decision making, and motor control.
It is the last to fully develop. It also keeps connections with other parts of the brain. This controls complex movements, things such as grasping or reaching for objects. It sends signals to the spinal cord that tells the premotor cortex create intentional and unified motions. This cortex also plays a role in decision making.
This cortex receives information from receptors that are on the skin. Areas with the most touch receptors on the skin appear in larger sections of the somatosensory cortex. This part of the brain is involved in cognitive processes that also include the consolidation of information from other senses. It also plays a role in recognition of faces and identification of things. Visual information is picked up by the occipital lobe from the retina, via the thalamus. It detects what, how and where we see. Located in the middle of the brain. It sorts out information from sensory and motor signals.
It also involved in regulation of consciousness and sleep. It is the neural connection that links both the left and right hemispheres of the brain. It receives information from the sensory systems, spinal cord, and other parts. Its main function is to regulates and detects errors in motor movements – coordination, balance, even muscular activities – making procedural memories.
Together, 9-11 make up the _brain stem_. Midbrain à responsible for reflexes, vision, and hearing. It is also associated with alertness. Pons à Relays sensory impulses. It regulates the depth of breathing and communication between the cortex and cerebellum.
Medulla à All nerve fibers are connected to the brain and spine. It controls visceral activities like heartbeat, respiration, circulation, digestion and its many reflexes. Responsible for memory, short terms and long term. It communicates with the rest of the brain because it is part of the limbic system.
The hippocampus can also create mental maps of things and can aid us in spatial memory. It links the central nervous system and the endocrine system. It functions as a control for hormones, regulating bodily function.
It specifically regulates the pituitary gland. Fighting, fleeing, feeding, sexual activities. Also, functions as a keeper of long term memories with the hippocampus, but its geared towards emotional events (episodic memory). It links fear, anxiety and aggression.
Together, 16-17 make up part of the _basal ganglia_. Subthalamic Nucleus à It ensures that enough time is taken to make correct decisions. It slows down decision making.
Putamen à Transfers information from the frontal cortex. It initiates learning of motor movements. Substantia Nigra à it initiates movements/motor control. It also has important roles with behaviors,
