E-mail email@example.com Abstract Background and Purpose—Injury-induced cortical reorganization is a widely recognized phenomenon. Methods—We used focal transcranial magnetic stimulation to map the cortical motor output area of a hand muscle on both sides in 13 stroke patients in the chronic stage of their illness before and after a 12-day-period of constraint-induced movement therapy.
Results—Before treatment, the cortical representation area of the affected hand muscle was significantly smaller than the contralateral side. Conclusions—This is the first demonstration in humans of a long-term alteration in brain function associated with a therapy-induced improvement in the rehabilitation of movement after neurological injury.

Tags: antipsychotics, big pharma, Johnson & Johnson, off-label marketing, Risperdal trackback Johnson & Johnson has come under fire recently for sundry illegal marketing practices related to the antipsychotic drug Risperdal (as enumerated here and here in legal documents, and here by a former J&J salesperson). “Recently” isn’t entirely accurate… considering that they were warned in 1994, 1999, and 2004 by the FDA to stop making “false and misleading claims” about Risperdal’s efficacy and superiority to other atypical antipsychotics, this has been a long time coming.

How Running For Our Lives May Have Made Humans Smarter. (ISNS) -- Could athletic prowess be linked to the size of our brains?
Some new research suggests that exercise-loving mice have larger midbrains then their more mellow counterparts. Scientists now think that the ability to run far and fast helped us evolve both physically and mentally. For evidence, look to the common house mouse. Scientists at the University of California, Riverside have taken house mice, bred for both their propensity and abilities on treadmill wheels, and found they had a larger section of their brain called the midbrain and other parts of the brain outside the cerebellum -- the motor control center -- than plain house mice. But the overall size of their brains did not vary significantly. Mechanisms and Functions of Theta Rhythms - Annu.-Rev.-Neurosci.-2013-Colgin.pdf. 1616.full.pdf. Brain (Hindbrain, Midbrain, Forebrain) Brain Unlike the spinal cord, which has changed little in structure during vertebrate evolution, the brain has changed dramatically.
A primitive linear brain, as seen in fishes and amphibians, expanded to form a deeply fissured and enormously intricate brain in the lineage leading to mammals (Figure 35-12). It reaches its greatest complexity in the human brain, which contains some 35 billion nerve cells, each of which may receive information from tens of thousands of synapses at one time. The ratio between weight of the brain and that of the spinal cord affords a fair criterion of an animal’s intelligence. In fish and amphibians this ratio is approximately 1:1; in humans the ratio is 55:1—in other words, the brain is 55 times heavier than the spinal cord.
Although the human brain is not the largest (the sperm whale’s brain is seven times heavier) nor the most convoluted (that of the porpoise is even more folded), it is by all odds the best in overall performance.

Chapter5 Animal Thought. 5 The functional organisation of the vertebrate brain Concepts of phylogenetic improvement in the organisation of the vertebrate nervous system have been (Bastian, 1880; Romer, 1949) and are (Razran, 1971; Romer and Parsons, 1977) rampant in accounts of comparative neuro-anatomy.
This may be because such concepts are accurate reflections of fact, but the reason may have more to do with the visibility of a topographical progression of structures in the plan of the vertebrate brain, which has in the past drawn evolutionary hypotheses irresistibly towards it. Hypothalamus. The hypothalamus is a small area at the base of the brain, weighing about 4 gm out of the 1400 gm brain weight of an adult human, yet it performs a wide range of functions that are vital for the survival of the individual.
In general, the hypothalamus acts as a integrator to regulate and coordinate basic functions necessary for life, such as fluid and electrolyte balance; feeding and energy metabolism; wake-sleep cycles; thermoregulation; stress responses; and sexual behavior and reproduction. Architecture of the hypothalamus Located just behind and between the eyes, the anterior border of the hypothalamus is formed by the optic chiasm. Neurologic Effects of Caffeine. Caffeine, or 1,3,7-trimethylxanthine, is related structurally to uric acid. It is metabolized by demethylation and oxidation. The major human pathway results in paraxanthine (1,7-dimethylxanthine), leading to the principal urinary metabolites, L-methylxanthine, 1-methyluric acid, and an acetylated uracil derivative.
Minor degradation pathways involve the formation and metabolism of theophylline and theobromine. No evidence exists to suggest that methylxanthines are converted to uric acid or that their ingestion can exacerbate gout. Doi:10.1016/j.neuroimage.2004.08.023 - pelchat_johnson_etal_NI2004.pdf.

Long Term Memory, Types of Memory and More. A long-term memory is anything you remember that happened more than a few minutes ago.
Novel storage mechanism allows command, control of memory. Introductions at a party seemingly go in one ear and out the other. However, if you meet someone two or three times during the party, you are more likely to remember his or her name. Your brain has taken a short-term memory -- the introduction -- and converted it into a long-term one. The molecular key to this activity is mTORC2 (mammalian target of rapamycin complex 2), according to researchers at Baylor College of Medicine in an article that appeared online in the journal Nature Neuroscience. "Memory consolidation is a fundamental process," said Dr. Mauro Costa-Mattioli, assistant professor of neuroscience at BCM and corresponding author of the report. Actin fibers For the last five decades, neuroscientists have known that making long-lasting memories is dependent on the ability of brain cells (neurons) to synthesize new proteins.
According to Costa-Mattioli's findings, mTORC2's role is evolutionarily conserved and likely relevant to humans. Long-Term Memory - Types of Memory. Long-term memory is, obviously enough, intended for storage of information over a long period of time. Despite our everyday impressions of forgetting, it seems likely that long-term memory actually decays very little over time, and can store a seemingly unlimited amount of information almost indefinitely. Indeed, there is some debate as to whether we actually ever “forget” anything at all, or whether it just becomes increasingly difficult to access or retrieve certain items from memory. Short-term memories can become long-term memory through the process of consolidation, involving rehearsal and meaningful association.
