Decoding Action Intentions in Parietofrontal Circuits Michael Vesia Marco Davare Single-unit studies in monkeys have implicated specialized parietofrontal circuits in processing sensorimotor information for goal-directed actions. The classical model of the neural control of reaching and grasping movements proposes that: areas located in the posteromedial portion of the intraparietal sulcus (IPS) contribute to the planning […]
Decoding Action Intentions in Parietofrontal Circuits Decoding intended goals from sensorimotor pathways of paralyzed patients is an important feature for cognitive neural prosthetics. However, it is not clear which brain areas, or combination of areas, are optimal to guide the selection of recording sites and the design and implementation of decoding algorithms. To date, the […]
My views on decision making, choice, executive function, cognitive workspace, emotions, consciousness I take from Paul Cisek – bottom line: “decisions” get made in the premotor brain areas, instantly. The following is a bit technical but if you don’t understand something — Google it!
It is a shame economists are so clueless about this basic biology – but they live in their own world. The related strange world of behavioral econ has no understanding over even awareness of this complexity. The term motivation refers to a construct that is widely used in psychology, psychiatry, and neuroscience. As is the […]
At some point business and policy makers are going to have to accept these scientific facts. It may take a generation of old thinkers dying off, however. The below post is excerpted from the full post here @ io9.com. Scientific evidence that you probably don’t have free will Humans have debated the issue of free […]
As predicted, white matter integrity was associated with probabilistic reward learning. [White matter is the structural infrastructure of the brain, not the processing part]. Specifically: increased white matter integrity in thalamocortical and corticostriatal paths was associated with better reward learning performance diminished integrity in these paths mediated the association between age and poor performance consistent […]
The best-laid plans: How we update our goals based on new information Princeton University researchers have identified mechanisms that govern how the brain incorporates information about new situations into our existing goals…. updating goals takes place in a region known as the prefrontal cortex, and appears to involve signals associated with the brain chemical dopamine.
