The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Researchers identify genetic factors responsible for neurons in the thalamus

The thalamus is the central translator in the brain: Specialized nerve cells (neurons) receive information from the sensory organs, process it, and transmit it deep into the brain. Researchers from the Institute of Toxicology and Genetics (ITG) of KIT have now identified the genetic factors Lhx2 and Lhx9 responsible for the development of these neurons.

JHN to initiate new Phase I immunotherapy trial in glioblastoma

Physicians at the Jefferson Hospital for Neuroscience (JHN), the region's only dedicated hospital for neuroscience, are tackling a particularly aggressive brain cancer that even surgery, chemotherapy and radiation often fail to treat with a promising new immunotherapy to attack a patient's tumor with their own cancer cells.

Stereotactic ablative radiotherapy may eradicate cancer

An innovative treatment technology could give cancer patients new hope for survival. In an international study based at Lawson Health Research Institute and London Health Sciences Centre's London Regional Cancer Program (LRCP), scientists are testing a therapy with the potential to eradicate cancers previously thought to be incurable.

First Total Artificial Heart implant performed at NewYork-Presbyterian/Columbia

Surgeons at NewYork-Presbyterian Hospital/Columbia University Medical Center performed the first Total Artificial Heart implant in the New York City area to replace a patient's dying heart.

Small genetic changes may increase risk of schizophrenia

Carrying single DNA letter changes from two different genes together may increase the risk of developing schizophrenia, Johns Hopkins researchers reported in the November 16 issue of Neuron.

Modern humans have a better sense of smell than Neanderthals

Compared to Neanderthals, modern humans have a better sense of smell. Differences in the temporal lobes and olfactory bulbs also suggest a combined use of brain functions related to cognition and olfaction. The increase of brain size is intimately linked to the evolution of humanity. Two different human species, Neanderthals and modern humans, have independently evolved brains of roughly the same size but with differing shapes. This could indicate a difference in the underlying brain organization.

Magnetic stimulation of brain nerve cells may speed up recovery from hemispatial neglect

Imagine waking up and being unable to see or recognize anything on the left side of your body. This condition, called hemispatial neglect, is common after a stroke that occurs on the right side of the brain. The current treatment of attention and concentration training using computer and pencil-and-paper tasks is inadequate.

Antioxidant can delay onset of all indicators of Alzheimer's

When you cut an apple and leave it out, it turns brown. Squeeze the apple with lemon juice, an antioxidant, and the process slows down. Simply put, that same "browning" process-known as oxidative stress-happens in the brain as Alzheimer's disease sets in. The underlying cause is believed to be improper processing of a protein associated with the creation of free radicals that cause oxidative stress.

Positive data from Nektar's NKTR-181 Phase 1 clinical study for chronic pain

Nektar Therapeutics today announced positive data from a Phase 1 clinical study of NKTR-181 evaluating multiple ascending oral doses of NKTR-181 over an 8-day treatment period in healthy subjects.

Acetylcholine can weaken synaptic connections between neurons in brain

Researchers from the University of Bristol have discovered that a chemical compound in the brain can weaken the synaptic connections between neurons in a region of the brain important for the formation of long-term memories.

People with Parkinson's exhibit increased arm swing during early stages

People with Parkinson's disease swing their arms asymmetrically -- one arm swings less than the other -- when walking. This unusual movement is easily detected early when drugs and other interventions may help slow the disease, according to Penn State researchers who used inexpensive accelerometers on the arms of Parkinson's disease patients to measure arm swing.

Link between high tau levels and worse outcome after head trauma

High levels of tau protein in fluid bathing the brain are linked to poor recovery after head trauma, according to a study from Washington University School of Medicine in St. Louis and the Fondazione IRCCS Ca Granda-Ospedale Maggiore Policlinico in Milan, Italy.

Nearly half of children with epilepsy experience adverse events due to invasive EEG

Some type of adverse event occurs in nearly half of children with severe epilepsy undergoing invasive electroencephalography (EEG) recordings, reports a study in the December issue of Operative Neurosurgery, a quarterly supplement to Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

Macrophages play a role in brown fat metabolism

Throughout the interior spaces of humans and other warm-blooded creatures is a special type of tissue known as brown fat, which may hold the secret to diets and weight-loss programs of the future.

GW scientist to identify molecular mechanisms that define embryonic OE stem cells

Anthony-Samuel LaMantia, PhD, professor in the Department of Pharmacology and Physiology and Director of the GW Institute for Neuroscience in the School of Medicine and Health Sciences has been awarded a grant from the National Institutes of Health to identify molecular mechanisms that define embryonic olfactory epithelium (OE) stem cells.

Researchers convert astrocytes directly into dopamine-producing neurons

In efforts to find new treatments for Parkinson's Disease (PD), researchers from the Perelman School of Medicine at the University of Pennsylvania have directly reprogrammed astrocytes, the most plentiful cell type in the central nervous system, into dopamine-producing neurons.
