... the differing parts of the parietal cortex can cause deficits in the perception of quantity (Walsh "Quantity" 2). Transcranial magnetic stimulation also induces phosphenes. Walsh reported that a moving magnetic field will induce an electric current in a nearby conducting body. The application of TMS to the brain causes a rush in electrical activity in the part of the brain to which it ... it can cause phosphenes which is the perception of light that can appear as flashes, blurs or simple geometrical patterns ("Phosphenes" 2). Phosphenes can be induced using transcranial magnetic stimul...

... retention of olfactory stimuli, while the receptor dDA1, also found in the mushroom body, is necessary for forgetting (Young-Cho, 2007). A negative olfactory memory can be formed by the artificial stimulation of the dopamine neurons in the PPL1 cluster paired with exposure to an odor, displaying the role of dopamine in the learning of Drosophila. The PPL1 cluster is a cluster of ... be put through conditioning before the test, where one odor (1) shall be presented and something mildly painful will happen to them, such as rough shaking of the vial or a small electric shock.

... , one was the accelerator and one was the brake. The basic findings were these. After the lateral hypothalamus was destroyed, animals stopped eating or drinking (Anand and Brobeck, 1951). Electrical stimulation of the same region would produce eating, drinking, or both behaviours. Conversely, lesions of the ventromedial hypothalamus produced overeating that led to gross obesity, whereas electrical ... stimulation suppressed eating (Hetherington and Ranson, 1942). However, Stricker and Zigmond (1976), reviewed the evidence and concluded that behvioural effects (catatonic behaviour of rats...
