Behavioural Neuroscience IV Neurons: The Building Blocks Introducing Neurons - A cell like other bodily cells o Cell body (soma) o Nucleus o Cell membrane, etc o Requires oxygen and fuel o Creates heat and waste - A cell has special structural and functional properties that let it function as part of an information processing system. Basic facts - There are about 100 billion neurons in the brain and spinal cord - There are 5 times as many “supportive” neuroglial cells - Neurons need glucose and oxygen to live; like all other kinds of cells in the body. - In the CNS, oxygen is also carried to the neurons in the cerebrospinal fluid. - On average, each neuron makes contact with 10, 000 others o That’s a bloody lot of interconnections o …and they can change (plasticity) - Analogy (cell as a powerful computing instrument ) o But not a dry, silicone based computer o A wet, messy, carbon based computer Connection - Sensory neurons o Receive and pass on input as a result of sensory stimulation
