These physical changes are made to the neuron, or the nerve cell, which controls something complex such as learning. The way they work is by sending electrical or chemical signals between each neuron. Just like anything functional, neurons have certain components that do certain things. Neurons are composed of…

caused by a deficiency in midline shh signaling from the brain in which there is an incomplete cleavage of prosencephalon into the left and right hemispheres which occurs sometime between the 18th and 28th day of gestation. The primary defect is the lack of forebrain tissue which is impacted by a lack of sonic hedgehog signaling which causes the facial defects. During the 4th week of gestation, the neural tube gives rise to the three primary brain vesicles prosencephalon, mesencephalon, and…

There are two types of cells in this system including the sensory nervous cells and the motor nervous cells. Sensory cells are responsible for carrying information to the brain…

that has show that various types of mental functions are reliant on localized brain activity. There have been several studies to that show localized brain activity, many of which the patient suffered a brain injury and neuropsychologist were able to determine which areas of the brain contribute to specific mental functions. Another type of study done was split-brain studies that show that the two hemispheres of the brain can develop two distinct consciousnesses when the corpus callosum…

in daily life. The ears and brain: a winning team For the sake of simplicity, let’s pretend our ears are a pair of microphones and our brain is a super-computer that evaluates all of the audio information coming from the ears. While there are some people who seem to lack a bit of RAM in their “computer”, we all have to admit that our brains are really amazing.
