Is there a conscious perception finish line?

Global workspace theory (GWT) is the proposition that consciousness is composed of contents broadcast throughout the brain.  Various specialty processes compete for the limited capacity of the broadcasting mechanisms, to have their content broadcast to the all the other specialty … Continue reading

Conscious visual perception happens in the frontal lobes

(warning: neuroscience weeds) Okay, switching back to the other major debate in neuroscience: whether conscious perception happens in the back or front of the brain.  A new study presents evidence that seems to bolster the frontal view: Neural Correlates of … Continue reading

The layers of emotional feelings

One of the ongoing debates in neuroscience is on the nature of emotions, where they originate, where they are felt, and how innate versus learned they are. One view, championed by the late Jaak Panksepp and his followers, see emotions … Continue reading
