In this episode, we hear about the emerging field of palaeoshellomics, wasp eggs that keep their food fresh, a monkey with a missing visual cortex, new biological methods inspired by astronomy and how to mix a family with a research career.
Molecular, genetic, and functional analysis is used to show that the olfactory Na+/Ca2+, K+ exchanger NCKX4 is expressed in cone photoreceptors and is critical for the wide operating range and high temporal resolution of cone-mediated vision.
Cerebellar Purkinje neurons use a multiplexed simple spike code combining synchrony/spike time and firing rate, with each component encoding distinct information about movements such as motion onset timing and kinematics.
The spatial and dynamic properties of self-motion signals are acquired at the first stage of otolith signal transformation, which is in the brainstem and cerebellum, and conserved across brainstem, cerebellar and cortical areas.
A hub in the rostral anterior cingulate cortex receives unusually high and functionally diverse inputs, providing a biological interface between motivation, incentive based learning, and decision making.
