Link Between Touch And Emotion Discovered
2012-06-05 04:36:07

Connie K. Ho for redOrbit.com Sight. Sound. Touch. These are just a few of the senses that the body has. This theme of senses was the subject of a recent study by neuroscientists from the California Institute of Technology (Caltech) who reported a relationship between touch and emotion via the brain´s primary somatosensory cortex. The findings, described in a recent issue of the Proceedings of the National Academy of Sciences (PNAS), were discovered by researchers Valeria Gazzola...

Researchers at the RUB and from Durham report Patients who are blind in one side of their visual field benefit from presentation of sounds on the affected side. After passively hearing sounds for an hour, their visual detection of light stimuli in the blind half of their visual field improved significantly. Neural pathways that simultaneously process information from different senses are responsible for this effect. "We have embarked on a whole new therapy approach" says PD Dr....

Research from Karolinska Institutet shows that the human olfactory bulb - a structure in the brain that processes sensory input from the nose - differs from that of other mammals in that no new neurons are formed in this area after birth. The discovery, which is published in the scientific journal Neuron, is based on the age-determination of the cells using the carbon-14 method, and might explain why the human sense of smell is normally much worse than that of other animals. "I've never...

Neurogenesis spurred by a high-fat diet encourages more eating and fat storage, animal study suggests New nerve cells formed in a select part of the brain could hold considerable sway over how much you eat and consequently weigh, new animal research by Johns Hopkins scientists suggests in a study published in the May issue of Nature Neuroscience. The idea that the brain is still forming new nerve cells, or neurons, into adulthood has become well-established over the past several...

Max Planck scientists discover brain cells in monkeys that may be linked to self-awareness and empathy in humans The anterior insular cortex is a small brain region that plays a crucial role in human self-awareness and in related neuropsychiatric disorders. A unique cell type — the von Economo neuron (VEN) — is located there. For a long time, the VEN was assumed to be unique to humans, great apes, whales and elephants. Henry Evrard, neuroanatomist at the Max Planck Institute...

Treatment of obstructive sleep apnea (OSA) in children normalizes disturbances in the neuronal network responsible for attention and executive function, according to a new study. "OSA is known to be associated with deficits in attention, cognition, and executive function," said lead author Ann Halbower, MD, Associate Professor at the Children's Hospital Sleep Center and University of Colorado Denver. "Our study is the first to show that treatment of OSA in children can reverse neuronal...

Young Birds Use Their Brain To Learn Songs
2012-05-21 08:55:04

Brett Smith for RedOrbit.com Male songbirds use a versatile part of the brain to learn their father´s song during the early stages of development, according to a report published yesterday in the online version of Nature. Researchers at the University of California at San Francisco (UCSF) found that Bengalese finch males use a trial-and-error method in learning the song they will use to attract a mate once they reach maturity. The learning process begins around 40 days after...

The baseline level of distrust is distinct and separable from our inborn lie detector Fool me once, shame on you. Fool me twice, shame on my parahippocampal gyrus. Scientists at the Virginia Tech Carilion Research Institute have found that suspicion resides in two distinct regions of the brain: the amygdala, which plays a central role in processing fear and emotional memories, and the parahippocampal gyrus, which is associated with declarative memory and the recognition of scenes....

Famous 1848 case of a man who survived a terrible accident has modern parallel Poor Phineas Gage. In 1848, the supervisor for the Rutland and Burlington Railroad in Vermont was using a 13-pound, 3-foot-7-inch rod to pack blasting powder into a rock when he triggered an explosion that drove the rod through his left cheek and out of the top of his head. As reported at the time, the rod was later found, "smeared with blood and brains." Miraculously, Gage lived, becoming the most famous...

Midbrain
2013-07-25 15:13:23

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...

Formation and Orientation The development of the brain is broken down into stages. The basic evolution begins in the third week of the embryonic process where the neural plate is formed. By week four, the neural plate has developed into the neural tube. The anterior part of the tube, the telencephalon, grows rapidly as it prepares to later give way to the brain. As time goes on, cells begin to classify themselves as either neurons or glial cells, thus determining their functions. Glial...
