The neural mechanisms underlying recovery of language after left hemisphere stroke remain elusive and are still debated after 130-years. Although older evidence suggested that right hemisphere language circuitry compensate for … Continue Reading Research upended as right-side of brain shown to aid in speech recovery after stroke.
The serotonin receptors, also known as 5-hydroxytryptamine receptors or 5-HT receptors, are a group of G protein-coupled receptors and ligand-gated ion channels found in the central and peripheral nervous systems. … Continue Reading Researchers identify previously unknown subtypes of 5HT neurons.
Cellular therapy for traumatic brain injury (TBI) has been suggested to replace cellular loss, restore growth factors homeostasis, repair damaged circuits and improve functional recovery. Stem cell therapy for TBI … Continue Reading Nano-magnetic cell targeting used to treat TBI in animal model.
The brain controls most of a person’s behaviour and changes in how brain areas work and communicate with each other can alter this behaviour and lead to impairments associated with … Continue Reading New neuroimaging technique shows how the ‘social brain’ is impaired in autism.
Differences in the size and structure of certain brain areas have been found in some adults diagnosed with schizophrenia. Early findings came from the discovery of enlarged ventricles in people … Continue Reading Neuroimaging matches specific schizophrenia behaviour to the brain’s anatomy.
In general, infertility is defined as not being able to get pregnant after one year of unprotected sex. Causes of infertility or reproductive problems include disease and aging, with male … Continue Reading Researchers identify specific neurons which activate fertility master switch.
Most mammalian tissues contain autonomous circadian clocks that are synchronized by the suprachiasmatic nuclei (SCN) in the brain. The SCN clock itself is entrained by external light cycles through retinal … Continue Reading Researchers identify how the mammalian retina bypasses the body’s circadian clock.
Humans are unique among social creatures in their willingness to bear personal costs to punish those who have harmed others. Despite the centrality of such third-party punishment decisions to modern … Continue Reading Neuroimaging identifies uniquely human brain region responsible for judgment.
Antidepressants are recommended as a first-line treatment of severe depression and for the treatment of mild-to-moderate depression that persists after conservative measures such as cognitive therapy. Experts recommend against their … Continue Reading Study maps structural brain changes caused by antidepressants.
Everyone occasionally feels blue or sad. However, these feelings are usually short-lived and pass within a couple of days. When a person has depression, it interferes with daily life. Depression … Continue Reading Study identifies new diagnostic brain protein in depression.
Around the turn of the 20th century, a Spanish neuroscientist named Santiago Ramón y Cajal created intricate images of intertwined neurons that changed neuroscience forever. His exquisite illustrations helped scientists … Continue Reading Researchers have developed single-cell imaging for the brain on the nanoscale.
Sudden unexpected death in epilepsy (SUDEP) is becoming increasingly recognized as a very real and devastating problem in which impaired breathing is thought to play a critical role. Researchers believe … Continue Reading Researchers begin to map unexpected death in epilepsy via neurostimulation in human study.
Researchers at the University of California, San Diego have found that the three-dimensional shape of the cerebral cortex, the wrinkled outer layer of the brain controlling many functions of thinking … Continue Reading First large-scale study finds topography of cerebral cortex differs with ancestral genetics.
The retina is a layer of tissue in the back of the eye that converts light into nerve impulses. The retina contains small, specialized neurons called bipolar cells that transmit … Continue Reading Researchers discover previously uncharted part of the eye.
Every time a person makes a memory, somewhere in their brain a tiny filament reaches out from one neuron and forms an electrochemical connection to a neighbouring neuron. A team … Continue Reading Mapping the neuroanatomy of a memory.
A study using intricate fiber dissection techniques provides new insights into the deep anatomy of the human brainstem and helps to define safe entry zones for neurosurgeons performing brainstem surgery, … Continue Reading Neurosurgeons map 3d microsurgical entry points for the human brainstem in unprecedented detail.
