Hi everyone,

Below is the abstract for Professor Staines' talk tomorrow. Hope to see you
there!

Crossmodal influences in somatosensory cortex: interaction of vision,
touch, and attention

Bimodal interactions between relevant visual and tactile inputs can
facilitate attentional modulation at early stages in somatosensory cortices
to achieve goal-oriented behaviors.  However, the specific contribution of
each sensory system during attentional processing and, importantly, how
these interact with the required behavioural motor goals remains unclear.
Experiments will be presented that used EEG and event-related potentials
(ERPs) to test hypotheses that activity from modality-specific
somatosensory cortical regions would be enhanced with task-relevant bimodal
(visual-tactile) stimuli and suppressed when the same stimuli were in
conflict for the behavioural task. Results show that specific
modality-specific somatosensory ERPs are modulated with attentional state
(either enhanced or suppressed) and this is related to the behavioural
impacts when presented in conflict. Transient inhibition of the
dorsolateral prefrontal cortex using transcranial magnetic stimulation
reduces these attention-based modulations of tactile ERPs. The functional
significance of this to sensorimotor behavior will be discussed.
