The interconnections and communication between different regions of the human brain influence behavior in many ways. This is also true for individual differences in higher cognitive abilities. The brains of more intelligent individuals are characterized by temporally more stable interactions in neural networksRead more
Researchers say that measuring how quickly a person’s pupil dilates while they are taking cognitive tests may be a low-cost, low-invasive method to aid in screening individuals at increased genetic risk for AD before cognitive decline begins.Read more
EPFL scientists are developing new approaches for improved control of robotic hands in particular for amputees that combines individual finger control and automation for improved grasping and manipulation.Read more
Salk researchers have discovered how neurons in the spinal cord help transmit such itch signals to the brain.Read more
Biochemists discover new insights into what may go awry in brains of Alzheimer’s patientsRead more
Researchers have now determined that strong, stable memories are encoded by “teams” of neurons all firing in synchrony, providing redundancy that enables these memories to persist over time.Read more
A team of scientists in Korea and the United States have invented a device that can control neural circuits using a tiny brain implant controlled by a smartphone.Read more
Scientist have identified a link between exposure to high levels of estrogen sex hormones in the womb and the likelihood of developing autism.Read more
Autism and other neurodevelopmental disorders often aren’t diagnosed until a child is a few years of age, when behavioral interventions and speech/occupational therapy become less effective.
But new research this week in PNAS suggests that two simple, quantifiable measures spontaneous fluctuations in pupil dilation or heart rate could enable much earlier diagnosis of Rett syndrome and possibly other disorders with autism-like features.
Biomedical engineers are helping develop a prosthetic arm for amputees that can move with the person’s thoughts and feel the sensation of touch via an array of electrodes implanted in the muscles of the patient.Read more
