Research May Offer a Unique Pathway for Targeting New Therapeutics for Addiction Treatment New York, NY (PRWEB) May 14, 2014 A research team from the Friedman Brain Institute of the Icahn School of Medicine at Mount Sinai published evidence showing that subtle changes of inhibitory signaling in the reward pathway can change how animals respond to drugs such as cocaine. This is the first study to demonstrate the critical links between the levels of the trafficking protein, the potassium...

Finding offers clue to developing treatments for misuse of illicit drugs Scientists today reported a possible basis for why food-restricted animals show increased susceptibility to drugs of abuse. This association has puzzled researchers since it was first observed more than three decades ago. Senior author Michael Beckstead, Ph.D., from the School of Medicine at The University of Texas Health Science Center San Antonio, said the team found that dopamine neurons in a brain region called...

Researchers at Northeastern University in Boston have developed a gene therapy approach that may one day stop Parkinson's disease (PD) in it tracks, preventing disease progression and reversing its symptoms. The novelty of the approach lies in the nasal route of administration and nanoparticles containing a gene capable of rescuing dying neurons in the brain. Parkinson's is a devastating neurodegenerative disorder caused by the death of dopamine neurons in a key motor area of the brain, the...

In a new study in Neuron, scientists identified specific key steps in the chain of events that causes stress-related drug relapse. They identified the exact region of the brain where the events take place in rat models and showed that by blocking a step, they could prevent stress-related relapse. All too often, stress turns addiction recovery into relapse, but years of basic brain research have provided scientists with insight that might allow them develop a medicine to help. A new study...

Light instantly triggers or reverses depression-like states in rodents -- NIH-funded studies A specific pattern of neuronal firing in a brain reward circuit instantly rendered mice vulnerable to depression-like behavior induced by acute severe stress, a study supported by the National Institutes of Health has found. When researchers used a high-tech method to mimic the pattern, previously resilient mice instantly succumbed to a depression-like syndrome of social withdrawal and reduced...

New MRI technique could help doctors track how patients respond to treatment A new imaging technique developed at MIT offers the first glimpse of the degeneration of two brain structures affected by Parkinson's disease. The technique, which combines several types of magnetic resonance imaging (MRI), could allow doctors to better monitor patients' progression and track the effectiveness of potential new treatments, says Suzanne Corkin, MIT professor emerita of neuroscience and leader of...

Using rabies virus, researcher tracks inputs to dopamine neurons A genetically-modified version of the rabies virus is helping scientists at Harvard to trace neural pathways in the brain, a research effort that could one day lead to treatments for Parkinson's disease and addiction. As described in a paper published on June 7 in the journal Neuron, a team of researchers led by Associate Professor of Molecular and Cellular Biology Naoshige Uchida used the virus to create the first-ever...

The midbrain, also known as the mesencephalon is the part of the brain most responsible for vision, motor control, arousal, temperature regulation, alertness and hearing. Formation and Orientation The midbrain is found under the cerebral cortex and above the hindbrain. The mesencephalon is not divided into any other portions of the brain unlike the other two vesicles that stem from the neural tube. There are four separate lobes on the side of the cerebral aqueduct within the...

attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
