Alzheimer’s disease is a neurodegenerative disorder characterized by progressive memory loss and cognitive dysfunction. It affects more than 30 million people worldwide, including an estimated 5.4 million Americans. One in … Continue Reading Dysfunction in neuronal transport mechanism linked to Alzheimer’s disease.
Epilepsy is a common neurological disorder in childhood. Epilepsy is more than twice as common in children as in adults. This statistic reflects the fact that epilepsy frequently remits in … Continue Reading Study shows that brain receptor which increases during puberty reduces epilepsy in mice.
A significant milestone in the evolution of the mammalian brain is the emergence of the corpus callosum, which is exclusively present in placental mammals. This commissure forms the largest axon … Continue Reading Neuroimaging shows that astrocytes are responsible for joining the 2 halves of the brain together.
It is known that neurons in the central nervous system of higher vertebrates are formed during embryonic development and that neurogenesis does not occur postnatally, except in the hippocampus. Buried … Continue Reading Researchers sucessfully make memories stronger and more precise during aging in mice.
The decision to engage in food-seeking behaviour depends on homeostatic signals relating to energy balance and the presence of competing motivational drives, as well as learned brain cues signaling food … Continue Reading Neuroimaging shows the effect of hunger on the brain’s response to food cues.
Alzheimer’s disease is characterized by the degeneration of neurons in the hippocampus and cortex, and the appearance of neuritic plaques and neurofibrillary tangles. Although the precise cause of Alzheimer’s disease remains … Continue Reading Researchers elevate brain protein to allay symptoms of Alzheimer’s in animal model.
It is known that nerves in the central nervous system of adult mammals do not usually regenerate when injured. However, the granule cell, a nerve cell located in the cerebellum, … Continue Reading Key molecule in the elusive regeneration of cerebellum synaptic connections identified.
For decades, scientists have known that people with two copies of a gene called apolipoprotein E4, or ApoE4, are much more likely to have Alzheimer’s disease at age 65 than … Continue Reading Study shows why people with the ApoE4 gene are more susceptible to Alzheimer’s disease.
Epigenetic dysfunction is implicated in many neurological and psychiatric diseases, including Alzheimer’s disease and schizophrenia. Consequently, histone deacetylases (HDACs) are being aggressively pursued as therapeutic targets. However, a fundamental knowledge … Continue Reading Researchers image the epigenetics of the human brain for the first time ever.
The rapid rise in obesity and associated spread of type 2 diabetes represent an enormous challenge for society, with no efficient and safe medicines to prevent or stop this development … Continue Reading Astrocytes shown to control sugar in the brain, as well as neurons.
Exercise is well-known for its cognitive benefits because it causes neurogenesis, the creation of new neurons, in the hippocampus, which is a key brain region for learning, memory and mood … Continue Reading Research refutes famous study, shows neurons created through exercise don’t erase old memories.
In the United States over 1.7 million cases of traumatic brain injury (TBI) are reported yearly, with the predictive correlation of cellular injury to impact tissue strain lacking, particularly for … Continue Reading First ever imaging of brain cells’ reactions to concussive trauma in real-time.
As they go about their everyday lives, people often have to choose between a safe option and a riskier one, such as staying in a secure job, or starting a … Continue Reading Study identifies neural circuits involved in making risky decisions.
Stem cells are non-specialized cells found in different organs, which have the capacity to generate specialized cells in the body. In the adult brain, neural stem cells give rise to … Continue Reading Study shows cerebrospinal fluid signals control the behaviour of stem cells in the brain.
In alcoholism and addictive drugs repeated exposure triggers glutamatergic and GABAergic plasticity in many neuronal populations. The dorsomedial striatum (DMS), a brain region critically involved in addiction, contains medium spiny … Continue Reading Researchers identify and successfully activate neurons that tell the brain to stop drinking.
The control of breathing is essential for life. Without an adequate response to increased carbon dioxide levels, people can suffer from breathing disturbances, sickness, and panic; in worst-case scenarios, it … Continue Reading Novel brainstem model show how the brain controls breathing.
