"Mind is such an odd predicament for matter to get into," says the poet Diane Ackerman. "If a mind is just a few pounds of blood, dream and electric, how does it manage to contemplate itself?

Introduction Early cortical representations of visual, auditory and somatosensory information (e.g. `primary' and `secondary' areas) are in the unimodal neocortex. In contrast, the cortical representations of the chemical senses (taste and smell) are in the limbic and paralimbic cortex. This is true in primates (e.g. Changes in brain activity related to eating chocolate Changes in brain activity related to eating chocolate
For the last 4 decades, the question of how to manipulate the serotonergic system with drugs has been an important area of research in biological psychiatry, and this research has led to advances in the treatment of depression. Research on the association between various polymorphisms and depression supports the idea that serotonin plays a role, not only in the treatment of depression but also in susceptibility to depression and suicide. The research focus here has been on polymorphisms of the serotonin transporter, but other serotonin-related genes may also be involved.1–5 In the future, genetic research will make it possible to predict with increasing accuracy who is susceptible to depression. Much less attention has been given to how this information will be used for the benefit of individuals with a serotonin-related susceptibility to depression, and little evidence exists concerning strategies to prevent depression in those with such a susceptibility.

Anatomy

Parietal Lobe Function The parietal lobes can be divided into two functional regions. One involves sensation and perception and the other is concerned with integrating sensory input, primarily with the visual system. The first function integrates sensory information to form a single perception (cognition). The second function constructs a spatial coordinate system to represent the world around us. Individuals with damage to the parietal lobes often show striking deficits, such as abnormalities in body image and spatial relations (Kandel, Schwartz & Jessel, 1991). Parietal Lobe Function
The transverse temporal gyri (also called Heschl's gyri or Heschl's convolutions) are found in the area of primary auditory cortex buried within the lateral sulcus of the human brain, occupying Brodmann area 41. It is the first cortical structure to process incoming auditory information. Anatomically, the transverse temporal gyri are distinct in that they run mediolaterally (towards the center of the brain), rather than front to back as all other temporal lobe gyri run. The transverse temporal gyri are active during auditory processing under fMRI for tone and semantic tasks. Transverse temporal gyrus Transverse temporal gyrus
The soft warm living substance of the brain and nervous system stands in stark contrast to the rigid metal and plastic hardware of a modern day computer, but at the fundamental level there are clear similarities between these two apparently disparate organizational systems and, of course, one is a product of the other. Not only are the nerve cell units (neurons) self-repairing and self-wiring under the grand design built into our genes, but they can also promote, amplify, block, inhibit, or attenuate the micro-electric signals which are passed to them, and through them. In this way they give rise to signalling patterns of myriad complexity between networks of cerebral neurons, and this provides the physical substrate of mind. These key processes of signalling by one group, or family, of neurons to another is achieved largely by the secretion of tiny quantities of potent chemical substances by neuronal fibre terminals. neurotransmitters and neuromodulators neurotransmitters and neuromodulators

BrainConnection.com - The Anatomy of Movement Susan Schwerin, PhD | March 5, 2013 Almost all of behavior involves motor function, from talking to gesturing to walking. But even a simple movement like reaching out to pick up a glass of water can be a complex motor task to study.

Beginning in the 1940s, Canadian brain surgeon Wilder Penfield mapped the brain's motor cortex -- the area that controls the movement of your body's muscles. He did this by applying mild electric currents to the exposed brains of patients while they were in surgery. Now you can relive his exploration of the brain. In the following feature we give you an electric probe and an exposed brain. All you need to do is shock and observe. A Science Odyssey: You Try It: Probe the Brain
Feedforward Neural Networks 2.5.1 Feedforward Neural Networks Feedforward neural networks (FF networks) are the most popular and most widely used models in many practical applications. They are known by many different names, such as "multi-layer perceptrons." Figure 2.5 illustrates a one-hidden-layer FF network with inputs
