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

The Brain Development and Violence Juanita S Farmer DeVry University Victimology Professor: Jeannine Quear What causes a person to become violent? Is a person born to be a killer or do social pressures cause a person to lash out? These are questions that scientists have been searching for answers to for decades. Though there are many theories about biological influences‚ there is no set rule that applies to everyone that explains what makes a person turn violent. There are three events that

A New theory on consciousness Abstract There has always been a clear distinction between what is considered rational thought and emotional behavior. The classical view is that rational thinking is more evolved than being emotional therefore the cortex‚ as a superb product of the evolution of brain must be responsible of the rational part of the self and the thalamic system‚ the one we share with birds and lizards must be the responsible of the emotions we feel. Nobody doubts that the thalamic

Brain tumors are abnormal growth of tissue in the brain or spinal cord. This abnormal growth disrupts the normal functions of the brain. Brain tumors are categories based on where they originated and whether they are cancerous or noncancerous. They can be benign which means they do not contain cancer cells‚ they grow slowly‚ and do not spread into other tissue. The tumors can also be malignant‚ which means they contain cancer cells and spread rapidly into surrounding tissue. ("Brain Tumors") Surgery

frequently associated with seizures. Studies & Research Studies were done to determine if somatic mtDNA (mitochondria DNA) mutations might contribute to the neurodegeneration observed in Huntington’s disease. Part of the research was to analyze cerebral deletion levels in the temporal and frontal lobes. Research hypothesis: HD patients have significantly higher mtDNA deletionlevels than agematched controls in the frontal and temporal lobes of the cortex. To test the hypothesis‚ the amount of mtDNA

The aim of this study was to investigate the effects of a deprived or enriched environment on neuroplasticity‚ in particular‚ the development of neurons in the cerebral cortex. The participants used were rats. The rats were separated and exposed to the two environments‚ one enriched with toys and one deprived with no toys for 30-60 days before being euthanized. Rats in the stimulating environment had a thicker cortex

desirable or dangerous. How does such recognition‚ which psychologists call preattentive perception‚ happen so accurately and quickly‚ even when the stimuli are complex and the context in which they arise varies? Much is known about the way the cerebral cortex‚ the outer rind of the brain‚ initially analyses sensory messages. Yet investigations are only now beginning to suggest how the brain moves beyond the mere extraction of features-how it combines sensory messages with past experience and with

According to Rilling (2014)‚ understanding the evolution of the unique characteristics of the human brain requires studying the brain of other living primate species. In other words‚ a specific evolutionary change in the human brain cannot be inferred to be unique to the human lineage unless other species sharing a last common ancestor don’t have it. That being said‚ Rilling emphasizes the role of comparative neuroimaging to investigate the similarities and differences between human and non-human
