The hippocampus is an important brain structure for recollection memory, the type of memory we use for detailed reliving of past events. Now, new research published by Cell Press in the December 22 issue of the journal Neuron reveals characteristics of the human hippocampus that allow scientists to use anatomical brain scans to form predictions about an individual's recollection ability. The new research helps to explain why this relationship has been hard to find in the past and provides...

Scientists model brain structure to help computers recognize objects An essential question confronting neuroscientists and computer vision researchers alike is how objects can be identified by simply "looking" at an image. Introspectively, we know that the human brain solves this problem very well. We only have to look at something to know what it is. But teaching a computer to "know" what it´s looking at is far harder. In research published this fall in the Public Library of...

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...

KIT Biologists Supply Major Results for Understanding the Thalamus, the “Relay Center” of the Brain 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. Their results contribute...

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 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. The findings, published today [13 Dec] in the...

The study, initiated by the Swiss researchers and published in Nature, constitutes ground-breaking work in exploring emotions in the brain. Anxiety disorders constitute a complex family of pathologies affecting about 10% of adults. Patients suffering from such disorders fear certain situations or objects to exaggerated extents totally out of proportion to the real danger they present. The amygdala, a deep-brain structure, plays a key part in processing fear and anxiety. Its functioning can...

Taxi Drivers' Brains Change Once Learning A City Map
2011-12-09 06:18:15

According to new research, the structure of a taxi drivers' brain actually changes during their training on how to navigate through a city's streets. The researchers studied taxi drivers in London, which is a city that consists of 25,000 streets and 20,000 landmarks. Trainees can take three to four years to learn the complicated streets and landmarks, and they must acquire what is known as "the Knowledge."  The trainees must pass a series of exams, only half of which ultimately...

A team of physicians and scientists at Barrow Neurological Institute, in collaboration with colleagues in the Ukraine, have written a first-of-its-kind biography of Ukranian anatomist and histologist Vladimir Betz. The article, "The Discovery of the Pyramidal Neurons: Vladimir Betz and a New Era of Neuroscience," appears in the November 2011 issue of the medical journal, Brain. Among other contributions, Vladimir Alekseyevich Betz (1834-1894) is best known for his discovery of Betz cells,...

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...
