Our editors will review what you’ve submitted and determine whether to revise the article. The midbrain, the upper portion of which evolved from the optic lobes, is the main centre of sensory integration in fish and amphibians. The left hemisphere controls the right half of the body, and vice versa, because of a crossing of the nerve fibres in the medulla or, less commonly, in the spinal cord. The gray matter is made up of about 100 billion neurons that gather and transmit signals while the white matter is made of dendrites and axons that the neurons use to transmit signals. I forgot my parents’ names and my favorite color. The surface of the cerebrum is called the cortex. A number of convolutions (called gyri) and fissures (called sulci) in the surface define four lobes—the parietal, frontal, temporal, and occipital—that contain major functional areas of the brain. Mammals also have an extra layer, the neocortex. The brain consists of the: 1. cerebrum 2. cerebellum 3. brain stem 4. diencephalon (thalamus and hypothalamus) 5. limbic system 6. reticular activating system The brain can be divided into two major parts: the lower brain stem and the higher forebrain. The Self-Made Human Brain Being Human 101: Science has discovered that the human brain is a workaholic. Glial cells (also known as glia or neuroglia) come in several types, and perform a number of critical functions, including structural support, metabolic support, insulation, and guidance of development. It is made up of more than 100 billion nerves that communicate in trillions of connections called synapses. This article is part of our course: Good Brain, Bad Brain: Basics.
