Neuroscientists Identify Source of Early Brain Activity

This image shows the selective response of a subplate neuron to sounds of different frequencies (horizontal axis) and volume levels (vertical axis). Warmer colors indicate a stronger response. Subplate neurons are among the first neurons to form in the cerebral cortex and were previously thought to serve a primarily structural role in brain development. A new study suggests that these neurons do, in fact, transmit sensory information. This cell only responded to higher frequencies, especially at low volume levels; increased volume expanded the cell's frequency range of response. Prior to this study, the ability of the cortex to selectively respond to certain sounds was thought to emerge later in brain development. Credit: Patrick Kanold

Brain researchers at ETH Zurich and other universities have shown for the first time that a region of the brain associated with empathy only activates very weakly in autistic people. This knowledge could help to develop new therapies for those affected by autism. Professor Nicole Wenderoth and her senior scientist Joshua Balsters have used fMRI from autistic adolescents to discover unusual activity in a particular region of the brain, the anterior cingulate cortex (ACC).

The researchers were aware that activity in this part of the brain is coupled with the “theory of mind”, which makes it possi...

Brain technique improves cognitive control

Stimulation of Dorsolateral Prefrontal Cortex Enhances Adaptive Cognitive Control: A High-Definition Transcranial Direct Current Stimulation Study Oyetunde Gbadeyan, Katie McMahon, Marco Steinhauser and Marcus Meinzer Journal of Neuroscience 14 December 2016, 36 (50) 12530-12536; DOI: https://doi.org/10.1523/JNEUROSCI.2450-16.2016

Stimulation of Dorsolateral Prefrontal Cortex Enhances Adaptive Cognitive Control: A High-Definition Transcranial Direct Current Stimulation Study Oyetunde Gbadeyan, Katie McMahon, Marco Steinhauser and Marcus Meinzer Journal of Neuroscience 14 December 2016, 36 (50) 12530-12536; DOI: https://doi.org/10.1523/JNEUROSCI.2450-16.2016

A cutting edge, non-invasive brain stimulation technique could improve cognitive control for people with conditions such as schizophrenia and autism, ADHD. Researchers at The University of Queensland’s Centre for Clinical Research have found the technique – which applies high-definition transcranial direct current stimulation to a particular area of the brain – improves cognitive and conflict control.

PhD candidate Oyetunde Gbadeyan said the study provides th...

Comparing your Index and Ring Fingers shows if you are likely to be Anxious or Good Athlete

Researchers used a common photocopy machine to measure the lengths of the index and ring fingers of 42 women. Half of these women were asked to solve different mental tasks after they had been given a drop of testosterone on their tongue. The goal was to determine the differences in how men's and women's brains work, and the significance of finger length and testosterone levels. Credit: Carl Pintzka / Kolbjørn Skarpnes, NTNU.

It is well-known that adults whose index finger is shorter than their ring finger were exposed to greater amounts of testosterone when they were in the womb. Both women and men with this characteristic are – on average – better equipped to solve mentally demanding 3D rotation tasks as adults...
