The roles of monkey M1 neuron classes in movement preparation and execution 15 Aug 2013 | 09:01 pm
The motor cortices exhibit substantial activity while preparing movements, yet the arm remains still during preparation. We investigated whether a subpopulation of presumed inhibitory neurons in prima...
Neural origin of evoked potentials during thalamic deep brain stimulation 15 Aug 2013 | 09:01 pm
Closed-loop deep brain stimulation (DBS) systems could provide automatic adjustment of stimulation parameters and improve outcomes in the treatment of Parkinson's disease and essential tremor. The evo...
Fear signaling in the prelimbic-amygdala circuit: a computational modeling and recording study 15 Aug 2013 | 09:01 pm
The acquisition and expression of conditioned fear depends on prefrontal-amygdala circuits. Auditory fear conditioning increases the tone responses of lateral amygdala neurons, but the increase is tra...
Female pheromones modulate flight muscle activation patterns during preflight warm-up 15 Aug 2013 | 09:01 pm
At low ambient temperature Helicoverpa zea male moths engage in warm-up behavior prior to taking flight in response to an attractive female pheromone blend. Male H. zea warm up at a faster rate when s...
Continuous theta-burst stimulation to primary motor cortex reveals asymmetric compensation for sensory attenuation in bimanual repetitive force produc... 15 Aug 2013 | 09:01 pm
Studies of fingertip force production have shown that self-produced forces are perceived as weaker than externally generated forces. This is due to mechanisms of sensory reafference where the comparis...
Saccade suppression exerts global effects on the motor system 15 Aug 2013 | 09:01 pm
Stopping inappropriate eye movements is a cognitive control function that allows humans to perform well in situations that demand attentional focus. The stop-signal task is an experimental model for t...
Discharge properties of abductor hallucis before, during, and after an isometric fatigue task 15 Aug 2013 | 09:01 pm
Abductor hallucis is the largest muscle in the arch of the human foot and comprises few motor units relative to its physiological cross-sectional area. It has been described as a postural muscle, aidi...
Effects of postural threat on spinal stretch reflexes: evidence for increased muscle spindle sensitivity? 15 Aug 2013 | 09:01 pm
Standing balance is often threatened in everyday life. These threats typically involve scenarios in which either the likelihood or the consequence of falling is higher than normal. When cats are place...
Global attractor alphabet of neural firing modes 15 Aug 2013 | 09:01 pm
The elementary set, or alphabet, of neural firing modes is derived from the widely accepted conductance-based rectified firing-rate model. The firing dynamics of interacting neurons are shown to be go...
A locomotor adaptation including explicit knowledge and removal of postadaptation errors induces complete 24-hour retention 15 Aug 2013 | 09:01 pm
Locomotor patterns are generally very consistent but also contain a high degree of adaptability. Motor adaptation is a short-term type of learning that utilizes this plasticity to alter locomotor beha...
