Title:                    How sensory systems collect evidence over time


Abstract:

In natural environments, most events are characterized by stochastic, 
“noisy” sensory signals. Noisy stimuli can be reliably identified only 
by accumulating evidence over time. We present studies designed to 
elucidate how an uncertain stimulus is integrated over time to produce a 
percept and how that percept is transformed into a decision. Our 
strategy is to compare human and rat performance to find fundamental 
underlying principles. From these principles we have constructed a model 
that accounts for all observed data. In behaving rats, neurons recorded 
from various regions of neocortex express the computations inherent to 
the model.
