MARIJUANA’S SHORT AND LONG TERM EFFECTS ON THE BRAIN Millions are abusing marijuana every day. In fact‚ 1 out of 7 high school students smoke marijuana more than once a day. Marijuana is taken very lightly and is the most highly used illegal drug. For this reason‚ society should know its short and long term effects on the brain. Marijuana can effect these two areas emotionally or physically. Also in some cases physical damages causes the emotional response. Although most public information

Materials The experiment measured participants response to stimulus‚ determining whether the cerebral hemispheres can communicate. Each test consisted of materials (a) the screen‚ and (b) the object. Being shown a word in either visual field tested the participants capability to process the visual stimulus‚ and share information between the cerebral hemispheres. Procedure Participants were positioned

resembles an afterimage from staring at a bright light‚ but it represents changes in orientation perception rather than in color or brightness. Most modem explanations of the MTAE are loosely based on the feature-detector model of the primary visual cortex (V1)‚ which characterizes this area as a set of orientation-detecting neurons. Experiments showed that these neurons became more difficult to excite: repeated presentation of oriented visual stimuli‚ and the desensitization persisted for some time

The limbic system and prefrontal cortex play an extensive role in human behavior. The limbic system is a set of structures within the brain that controls human emotions and memories; intensifying during puberty. On the other hand‚ the prefrontal cortex is responsible for regulating behavior and thought analysis. This is developed later than the limbic system which has already begun developing during puberty as stated earlier. Due to the differences in developmental time‚ the extremities such as‚

Transcranial magnetic stimulation (TMS) has become a practical and effective technique in its use to study cognitive function (Jahanshahi & Rotherwell‚ 2000). It has been used to explore the motor-cortex‚ through its visible muscle twitch effect after stimulation‚ and primary visual pathways (Jahanshahi & Rotherwell; Beckers & Zeki‚ 1995). Through this exploration it was found that TMS can be used to create ‘virtual lesions’ in the brain in which cortical processing is disrupted (Jahanshahi & Rotherwell)
