The results have important implications for the role of NMDA-R in cognitive function. They also provide insight to the role of the NMDA-R in the pathophysiology of neuropsychiatric disorders such as Schizophrenia.

We then tested these experimentally using the NMDA-R antagonist ketamine - which produced decision making deficits consistent with a lowering of excitation inhibition (E/I) balance.

The circuit relied on NMDA-R activity, and we simulated the effects of NMDA-R hypofunction onto either pyramidal cells or interneurons. These two perturbations made dissociated predictions for behaviour.

We used psychophysics to reveal irrational biases in evidence accumulation decisions. We then used a spiking circuit to reveal a neural mechanism for these biases.

Our results suggest that the brain uses fast (150ms) covert mechanisms for guiding fixations toward highly valuable and novel information. By employing such covert mechanisms, fixation behavior becomes dissociable from the value comparison processes that drive choices [8/8]

Finally, we confirmed our subjects were making choices with a similar decision mechanism to previous human studies. We showed that how long a stimulus was fixated influenced its likelihood of being chosen [7/8]pic.twitter.com/ffRHp4EQ5c

A further dissociation between fixations and choices was shown on Mixed trials (overtrained vs. novel stimulus) - there was a strong bias toward fixating the novel stimulus first, but no bias toward choosing it [6/8]pic.twitter.com/KaO0HksyUd

For novel stimuli, 1st fixations became more value-driven across a session – as subjects gained more experience of the stimuli. However, this improvement lagged behind learning of accurate choices, suggesting separate processes governed the learning of fixations and choices [5/8]pic.twitter.com/eRXqG3slKd

The first fixation latency was fast (∼150 ms) but, surprisingly, its direction was value-driven. This suggests covert evaluation of stimulus values prior to first saccade. This was particularly evident for overtrained stimuli [4/8]pic.twitter.com/NtL6SC2QOz

Subjects made binary choices between reward predictive stimuli which were well-learned (overtrained), recently learned (novel), or a combination of both (mixed). They were free to saccade around the options and make a choice at any time with a joystick [3/8]pic.twitter.com/AKw0yg9EqQ

Previous work has shown that where we direct our gaze can have a big impact on what we choose. However, where we choose to gaze during the decision process is not well-characterised, despite the important role it plays [2/8]
