The Brain-Targeted Chapter 2

- I am writing this chapter's reaction with more notes and facts than anything so I can remember the parts of the brain. -

BRAIN CELLS: NEURONS & GLIAL CELLS
*Neurons are nerve cells that receive and transmit information to the other cells through electrochemical signals. This process is essential for the essence of brain functioning.

*Glial cells account for more than half of the brain's volume and far out number neurons. This cells provide structurual support to the neurons.

CEREBRAL ORGANIZATION
*Hindbrain: Consists of the pons, medulla oblongata and cerebellum.

*Pons & Medulla Oblongata: These functions control autonomic functions such as respirations, heart rhythm and states of consciousness. They also control sensory information.

*Cerebellum: This part of the brain contains approximately 11 billion cells, that control important motor and sensory functions.

 

*The Limbic System: Consists of the thalamus, hypothalamus, hippocampus and amygdala.

 

*Thalamus: This part serves as the traffic cop, directing information received from the sense to other parts of the brain for further processing.

 

* Hypothalamus: This part serves as a relay station as it monitors information coming from the autonomic nervous system.

 

* Hippocampus: This part holds memories of the immediate past and serves to consolidate memories into the long-term memory system.

 

* Amygdala: This part is mostly associated with emotional states and processes. It is especially involved in our response to fear.

 

 

 





*The Cerebrum: This is the largest area of the brain and it is divided into hemispheres.

 

* Occipital Lobe: This part perceives and processes visual stimuli and their properties.

 

* Temporal Lobe: This area specializes in processing spoken language.

 

* Parietal Lobe: This area is responsible for processing sensory information such as pain and body temperature.

 

* Frontal Lobe: This area deals with executive functions such as planning, carrying out actions and inhibiting responses.
