Alpha oscillations are ubiquitous in the brain, but their role in cortical processing remains a matter of debate. Recently, evidence has begun to accumulate in support of a role for alpha oscillations in attention selection and control. Here we first review evidence that 8–12 Hz oscillations in the brain have a general inhibitory role in cognitive processing, with an emphasis on their role in visual processing. Then, we summarize the evidence in support of our recent proposal that alpha represents a pulsed-inhibition of ongoing neural activity. The phase of the ongoing electroencephalography can influence evoked activity and subsequent processing, and …

Even though there are millions of neurons in our brain, in neurodegenerative diseases only a select set of neurons show vulnerability and progressively degenerate. In amyotrophic lateral sclerosis (ALS), motor neurons in the cortex and spinal cord show selective vulnerability. Their progressive degeneration results in lack of control over voluntary movement, without affecting memory and cognitive function. We are developing novel approaches to understand cellular and molecular mechanisms responsible for motor neuron degeneration. Our findings will allow cell-based therapeutic interventions in the near future.

Prior research has shown that the orbitofrontal cortex (OFC) plays an important role in the representation of the evaluation of stimuli, regardless of stimulus modality. Based on these findings, researchers have proposed that the OFC serves a common currency function, allowing for the direct comparison of different types of perceptual stimuli (e.g. food, drink, money). The present study was designed to extend this research and investigate whether these same regions of OFC that have been identified in previous research are involved in evaluating imagined stimuli. Specifically, we asked participants to draw on prior attitudinal knowledge to generate internal representations of …
