How Each Movement Changes the Next: An Experimental and Theoretical Study of Fast Adaptive Priors in Reaching
Most voluntary actions rely on neural circuits that map sensory cues onto appropriate motor responses. One might expect that for everyday movements, like reaching, this mapping would remain stableExpand

Transcranial magnetic stimulation of posterior parietal cortex affects decisions of hand choice
Deciding which hand to use for an action is one of the most frequent decisions people make in everyday behavior. Using a speeded reaching task, we provide evidence that hand choice entails aExpand

Early life environment modulates ‘handedness’ in rats
Right handedness is one of the most prominent markers of human functional brain asymmetry. Deviation from this norm appears to be associated with certain developmental disorders. While many studiesExpand

Dynamic Sensorimotor Planning during Long-Term Sequence Learning: The Role of Variability, Response Chunking and Planning Errors
Many everyday skills are learned by binding otherwise independent actions into a unified sequence of responses across days or weeks of practice. Here we looked at how the dynamics of action planningExpand

Adolescent brain development and depression: A case for the importance of connectivity of the anterior cingulate cortex
We propose that structural and functional connectivity of the anterior cingulate cortex (ACC) represents a critical component of adolescent developmental psychopathology. We hypothesize thatExpand

High-definition fiber tracking for assessment of neurological deficit in a case of traumatic brain injury: finding, visualizing, and interpreting small sites of damage.
For patients with traumatic brain injury (TBI), current clinical imaging methods generally do not provide highly detailed information about the location of axonal injury, severity of injury, orExpand

Anticipatory adjustments in the unloading task: Is an efference copy necessary for learning?
Abstract. In the unloading task, a weight is held in the palm of one hand. When an external agent removes the weight, an upward perturbation of the loaded hand is observed. However, when a personExpand

Brain dynamics of post‐task resting state are influenced by expertise: Insights from baseball players
Post‐task resting state dynamics can be viewed as a task‐driven state where behavioral performance is improved through endogenous, non‐explicit learning. Tasks that have intrinsic value forExpand

Brain volume and white matter in youth with type 2 diabetes compared to obese and normal weight, non-diabetic peers: A pilot study
Type 2 Diabetes Mellitus (T2DM) and obesity are linked to specific patterns of subcortical brain atrophy and decreased microstructural integrity of white matter. Fifteen adolescents (12–21‐years‐old,Expand

Corticostriatal synaptic weight evolution in a two-alternative forced choice task
TLDR
In natural environments, mammals can efficiently select actions based on noisy sensory signals and quickly adapt to unexpected outcomes. Expand
