Hello! I am writing a paper for my psychology class, and I need you to help me with my first part, which is: how does the brain work. I collected some information that I would like you to summarise smoothly so it won’t be plagiarism (because it is mainly just copying paste), and basically it just describes in a page how the brain works.
“The brain contains billions of nerve cells arranged in patterns that coordinate thoughts, emotions, and behaviors. Nerves connect the brain to the rest of the body, so communication can occur in split seconds.
The cerebrum is the largest part of the brain. The outermost layer of the cerebrum is the cerebral cortex, the “gray matter” of the brain. Deep folds and wrinkles in the brain increase the surface area of the gray matter, so more information can be processed.
The cerebrum is divided into two halves (hemispheres) by a deep fissure. The hemispheres communicate with each other through a thick tract of nerves, called the corpus callosum, at the base of the fissure. In fact, messages to and from one side of the body are usually handled by the opposite side of the brain. Finally, brain’s hemispheres are divided into four lobes.
The frontal lobes control thinking, planning, organizing, problem solving, short-term memory and movement.
The parietal lobes interpret sensory information, such as taste, temperature and touch.
The occipital lobes process images from your eyes and link that information with images stored in memory.”
The occipital lobes process images from your eyes and link that information with images stored in memory.
The temporal lobes process information from your senses of smell, taste and sound. They also play a role in memory storage.
The cerebellum is a wrinkled ball of tissue below and behind the rest of the brain. It works to combine sensory information from the eyes, ears and muscles to help coordinate movement.
The brainstem links the brain to the spinal cord. It controls many functions vital to life, such as heart rate, blood pressure and breathing. This area is also important for sleep.
Structures deep within the brain control emotions and memories. Known as the limbic system, these structures come in pairs. Each part of this system is duplicated in the opposite half of the brain.
The thalamus acts as a gatekeeper for messages passed between the spinal cord and the cerebral hemispheres.
The hypothalamus controls emotions. It also regulates the body’s temperature and controls crucial urges — such as eating or sleeping.
The hippocampus sends memories to be stored in appropriate sections of the cerebrum and then recalls them when necessary.
Nerve cells (neurons) have two main types of branches coming off their cell bodies. Dendrites receive incoming messages from other nerve cells. Axons carry outgoing signals from the cell body to other cells — such as a nearby neuron or muscle cell.
Interconnected with each other, neurons are able to provide efficient, lightning-fast communication.
A nerve cell (neuron) communicates with other cells through electrical impulses when the nerve cell is stimulated. Within a neuron, the impulse moves to the tip of an axon and causes the release of neurotransmitters, chemicals that act as messengers.
Neurotransmitters pass through the synapse, the gap between two nerve cells, and attach to receptors on the receiving cell. This process repeats from neuron to neuron, as the impulse travels to its destination — a web of communication that allows you to move, think, feel and communicate.
These are all the information’s I want you to work with, thank you so much for your time!
