Some people can pass a hearing test but have trouble understanding speech in a noisy environment. New research identifies a new mechanism for this condition just years after its discovery.
In a new study, researchers found for the first time that the neurotransmitter dopamine is involved in human bonding, bringing the brain's reward system into our understanding of how we form human attachments. The results, based on a study with 19 mother-infant pairs, have important implications for therapies addressing postpartum depression as well as disorders of the dopamine system such as Parkinson's disease, addiction, and social dysfunction.
5-hydroxytryptamine subtype 6 receptor (5-HT6R) has been extensively considered as a promising therapeutic target for the treatment of neuropathological disorders. 5-HT6R were hypothesized to be implicated in the processes of learning, memory retention, and cognition. Several selective 5-HT6R ligands are currently undergoing clinical trials for treatment of Alzheimer's disease and schizophrenia, SB-742457 and Lu-AE-58054.
MRC researchers at the University of Leicester have shed light on critical gene network involved in neurological disease.
Fathers given boosts of the hormone oxytocin show increased activity in brain regions associated with reward and empathy when viewing photos of their toddlers, an Emory University study finds.
Through the use of wearable digital devices, BU's Rhoda Au is collecting an enormous amount of data on people over time with the hope of finding the minute physical changes that correspond with the slow mental decline of Alzheimer's.
Researchers have developed an improved type of electrode that is more durable, lasts longer in the body and transmits a clearer, more robust signal than electrodes made from current state-of-the-art materials. This could allow for improved restoration of mobility after spinal cord accidents, as well as improved powered prosthetic limbs.
Screen time before bed can mess with your sleep. But people without TV and laptops skimp on sleep too, researchers say. A Duke University study of people living without electricity or artificial light in a remote farming village in Madagascar finds they get shorter, poorer sleep than people in the US or Europe. But they seem to make up for lost shuteye with a more regular sleep routine, the researchers report.
A new study published by UAlberta researchers in the journal Alzheimer's and Dementia: Translational Research and Clinical Intervention examines if a compound called AC253 can inhibit a 'rogue' protein called amyloid. The protein is found in large numbers in the brains of Alzheimer's patients and is suspected to be a key player in the development of the disease.
Tumors that originate in other organs of the body and spread to the brain are known as metastatic brain tumors. According to the American Brain Tumor Association, this tumor type is the most common in adults, affecting as many as 300,000 people each year. University of Missouri School of Medicine researchers compared two common postsurgical therapies for metastatic brain tumors and found that stereotactic radiosurgery can provide better outcomes for patients compared to whole-brain radiation.
