afferents converging from local and distant areas onto the same neuron in the spinal cord.2 Limitations to this theory is that the pain should be bi-directional & should occur at the same time. Due to both of the afferents converging on the same neuron a noxious stimulus in one area should trigger pain in the other this is not the case for referred pain. Similar to the bifurcation theory due to both afferents synapsing with the same neuron the pain should occur at the same time.2

question is are the mind and the brain the same entity or are they separate entities within a person’s head? It is undisputed that the actions of the mind are within the brain. But are the actions of the mind only neurological impulses sent between neurons within the brain or is the mind something more? There are two theories that will be focused upon concerning the mind/brain arguments‚ dualism and monism. The explanation of the functionality of the mind and brain‚ along with the theories of monism

and‚ consequently‚ your mental experiences with a Silicone brain would be the same as with your current Carbon brain. At a higher organizational level‚ each neuron could be replaced by an electrical device that performs the same function the neuron performs. These electrical devices would be connected to each other in the same way your neurons are currently connected to each other and therefore perform the same function - including producing a mental world. It is only one step further to replace the

Neuropeptide are produced in cells derived from ambryonic neural precursor structures‚ these include neurons‚ chromaffin cells of the adrenal medulla‚ enterochromaffin cellsof the gut and islet cells of the pancreas. The neuropeptides precursors are protein molecules. The protein precursors for each type of peptide are made in the cell body which is the site of almost all protein synthesis in the neuron. The protein is packed into large vesicles with enzymes. These vesicles are transported to the axon

The nerve impulse The information is transmitted by polarity changes in the membranes of cells due to the presence of neurotransmitters that alter the ionic concentration inside the cell. Moreover‚ inside the neuron proteins and ions are negatively charged . This difference in ion concentration also produces a potential difference between the outer membrane and within the cell . The value reached is about -70 millivolts (negative inside with respect to the value of positive charges outside

Explain what is meant by this phrase. This means that once the threshold is met‚ an action potential occurs. If the stimulus is too small an action potential does not occur. An action potential is usually initiated in an axon at or near what? The axon hillock‚ the initial segment‚ and the trigger zone. The adequate stimuli
