A new analysis suggests that Parkinson's disease can be understood in terms of damage to control circuits in the brain responsible for habits. Removing part of the brain can help patients regain smooth initiation of movements by reducing inhibitory signals from malfunctioning habitual control systems.
Researchers discovered that specific brain circuits in the basal ganglia signal the start and stop of new actions, a process compromised in Parkinson's and Huntington's patients. Genetic manipulation of these circuits in mice impaired sequence learning, echoing human patients' struggles with movement initiation and termination.
Researchers at the University of Pittsburgh have found evidence that the basal ganglia and cerebellum are linked together to form an integrated functional network. This discovery has important implications for understanding Parkinson's disease and dystonia, and may lead to new treatment approaches.
A new study from Karolinska Institutet finds that the limbic striatum, an evolutionarily old part of the brain, is involved in implicit learning of motor sequences. This discovery sheds light on fundamental learning systems shared with primitive vertebrates and has implications for developing treatments for diseases like Parkinson's.
Researchers found that brain initially stores improvements in one pathway before transferring to motor pathway for long-term storage. Young zebra finches learn to sing by mimicking their fathers' song and eventually master the syllables and rhythms through repeated practice.
Researchers have uncovered structural features of the brain that may contribute to the development of ADHD. The study used a new analysis tool to examine shape differences in the brains of children with ADHD and found significant abnormalities in boys, but not girls.
A new brain imaging study reveals that there are optimal times for multitasking, allowing individuals to be more efficient. The research found that certain brain regions show higher activity when people are performing well under multiple tasks.
A team of researchers has made a groundbreaking discovery in the Movement, Adaptation, Cognition Laboratory, revealing an interaction at the cellular level between cognitive information and motor information. This finding provides a fundamental advance in understanding the physiological role of the basal ganglia and has significant imp...
A University of Pittsburgh study identifies specific brain regions involved in anorexia nervosa, including the basal ganglia and its relation to reward and reinforcement. The research suggests that altered dopamine function may contribute to the disorder's symptoms, including obsessive behaviors and self-denial.
Researchers have made significant strides in understanding the brain circuits responsible for tics in Tourette's syndrome. Studies suggest an imbalance in the basal ganglia's inhibitory function may lead to the disorder's characteristic symptoms. Increased activity in certain regions, such as the ventral striatum, and altered neuronal ...
Researchers found that signals from the basal ganglia may be preventing intact visual areas from functioning properly. Disrupting basal ganglia activity could restore balance and treat visual neglect, a condition where patients perceive only half of their surroundings.
Researchers examined two groups of children ages five to 10 years with prenatal alcohol exposure and found impaired ability to perceive and utilize temporal information. Alcohol-exposed children demonstrated slower and less efficient responses, particularly those with lower IQs.
A new study published in Nature reveals that increased activity in one brain system is associated with decreased activity in another during learning of a simple skill. The findings suggest new strategies for dealing with learning disorders and diagnosing Alzheimer's disease, as well as a better understanding of brain plasticity.
