Dementia is a common illness with an incidence that is rising as the aged population increases. A multitude of neurodegenerative illnesses have an associated dementia, including corticobasal degeneration, Creutzfeldt–Jakob disease, … Continue Reading Brain map researchers release first of it’s kind data on the aging human brain and traumatic brain injury.
Presently, there are limitations to drug delivery to the brain as it is tightly protected by the blood-brain barrier. The blood-brain barrier is a protective barrier which separates the circulating … Continue Reading Researchers derive first ever molecular model of critical blood-brain barrier transporter.
Whenever a person learns something new or is affected by their experiences it’s because synapses, the connections between neurons in the brain, have changed. Sometimes new synapses are made, and … Continue Reading Study shows how astrocytes help control synapse strength and plasticity.
In patients with Parkinson’s disease, gait disorders and difficulty with balance are often caused by the degeneration of a specific type of neuron, called cholinergic neurons, in a region of … Continue Reading New technique begins to map and untangle neuronal networks in Parkinson’s disease.
Dendritic spines are specialized protrusions responsible for receiving excitatory synaptic inputs, providing an important function in communication between neurons. The majority of excitatory synapses in the brain exist on dendritic … Continue Reading Novel molecule promotes the neuronal structures associated with memory to grow.
Neuropathic pain is deﬁned as pain initiated or caused by a primary lesion or dysfunction in the nervous system. Chronic neuropathic leg pain is the most common form of neuropathic … Continue Reading Neuroimaging shows that spinal cord stimulation reduces emotional aspect of chronic pain.
Primary progressive aphasia (PPA) is a form of dementia characterized by degeneration of the language network. In the early stages, PPA is associated with a left-lateralized pattern of cortical atrophy … Continue Reading Neuroimaging can identify start and location of amyloid plaques in living brain.
The auditory nerve is comprised of thousands of tiny nerve fibers responsible for transmitting sound to and from the ear and the brain. Recent discoveries have shown that they are … Continue Reading Researchers identify previously unknown compensatory brain amplifier for hear loss.
Major depressive disorder is a highly familial illness and the leading cause of disability worldwide for persons 15 to 44 years of age. It is associated with increased mortality resulting … Continue Reading Study shows that both genetics and environment impact depression.
Signs of autism, schizophrenia and bipolar disorder often take years to manifest. Studying suspect disease genes in the brain early in life could prove valuable in the development of new … Continue Reading Study maps autism-linked protein in neurodevelopment.
Neuroplasticity, or brain plasticity, is an umbrella term that describes lasting change to the brain throughout life. One of the fundamental principles of how neuroplasticity functions is linked to the … Continue Reading Researchers identify previously unknown subtype of neuron in the visual cortex.
Low levels of serotonin in the brain are known to play a role in depression and anxiety, the involvement of serotonin (5-HT) in regulating emotional behaviour is firmly established. In … Continue Reading Researchers uncover new serotonin neuronal mechanism in depression.
Cocaine is a strong central nervous system stimulant that increases levels of the neurotransmitter dopamine in brain circuits regulating pleasure and movement. Normally, dopamine is released by neurons in these … Continue Reading Researchers begin to map brain regions and circuits changed by cocaine-use.
Obesity is a significant risk factor for cardiovascular disease, diabetes, and cancer. Although obesity can stem from behavioural factors such as diet and physical inactivity, central nervous system changes can … Continue Reading Neuroimaging maps areas of the brain in obese children activated by food odours.
Ghrelin is a peptide released from the empty stomach into circulation, and which acts on the brain to promote appetite. Recent studies showed that ghrelin also affects learning and memory, … Continue Reading Study identifies previously unknown mechanism of memory formation in the brain.
While some things may be ‘as simple as black and white,’ this has not been the case for the circuits in the brain that make it possible for a person … Continue Reading Study visualises, maps cortical circuits that encode black and white for the first time.
