brain

Introduction

your brain can be considered the most complex organ in your body and the centerpiece of your nervous system.

Althought your brain work as a unified whole neuroscientist can identify areas within it  than perform functions. Your brain is organized into three interconnected layers: the central core, limbic system, and cerebral cortex, all of which contain structures that regulate everyday life. Explore the human brain and its role in regulating your life.

Central  core

The central core is found in all vertebrates. Its five main regions help regulate basic life processes, including breathing, pulse, arousal, movement, balance, sleep, and the early stage of processing sensory information.

:::::::::::::::::::central core::::::::::::::

*Thalamus

*pons

*cerebellum

*reticular formation

*medulla

Limbic system

The limbic system exists only in mammals. Its regions mediate motivated behaviors, emotional states, and memory processes. The limbic system also regulates body temperature, blood pressure, blood sugar level, and other housekeeping activities.

*Hippocampus

*Amygdala

*hypothalamus

Cerebral cortex

The cerebral cortex directs the brain's higher cognitive and emotional functions. It is divided into two almost symmetrical halves called the cerebral hemispheres. Each  hemisphere contains four lober. Areas witing these lobes oversee all forms of conscious experience, including perception, emotion, thougth, and planning, as well as many unconcious cognitive and emotional processes.
