Dopamine conducts prefrontal cortex ensembles
Dopamine activation controls the ensemble activity of neurons and increases oscillatory activity in the prefrontal cortex.... Read More...
Maternal diet during pregnancy may modulate the risk of ADHD symptoms in children
The risk of a child being diagnosed with ADHD may be modulated by the mother's diet while pregnant. Analyzing umbilical cord samples, researchers discovered a higher omega-6:omega-3 ratio was associated with an increased risk of ADHD in children during mid-childhood.... Read More...
Differences in brain activity in children with anhedonia
Using fMRI to examine the brains of children while resting, researchers discover anhedonia is associated with hyperconnectivity between the cingulo-opercular network and ventral striatum.... Read More...
First double-blind controlled trial of TNS shows reduced symptoms in some children with ADHD
Researchers report trigeminal nerve stimulation, administered during sleep, is both effective and safe for treating ADHD in children. The study reveals the treatment helps to reduce behavioral symptoms of ADHD and increases activity in brain circuits that modulate hyperactivity. ... Read More...
Smoking During Pregnancy Increases ADHD Risk 3 Fold
A new study links prenatal smoking with a significantly increased risk of a child developing ADHD later in life. The study found higher cotinine levels in the mother's blood during pregnancy increased the risk of her child being diagnosed with ADHD three fold. ... Read More...
Ritalin Has No Effect on Primate Prefrontal Cortex
Even at doses that help improve monkeys' attention, researchers observe no differences of neural activity in the prefrontal cortex after administering Ritalin.... Read More...
Genetic Study of Impulsiveness Reveals Link with Psychiatric Disorders
Researchers have identified a genetic link between impulsivity and a predisposition to engage in risky behaviors. ... Read More...
Link Between Psychiatric Disorders and Events During Prenatal Development Identified
A new study reports genetic variants that are critical for the development of the brain during fetal development are also frequently found in psychiatric disorders.... Read More...
Brain Pathway Linked to Impulsive Behaviors Identified
A new study reveals impulsive behaviors may be triggered when dopamine passes from the amygdala to the BNST.... Read More...
All Too Human: The Price We Pay for Our Advanced Brains May Be a Greater Tendency to Disorders
Researchers report the neural code of the prefrontal cortex is more efficient than the amygdala in both humans and primates. The lower resistance of the amygdala to errors in humans may play a role in exaggerated survival responses, such as those seen in anxiety and PTSD.... Read More...
