Nonhuman primate research to lose federal funding at major European facility The Dutch Senate has ordered the Biomedical Primate Research Centre in the Netherlands to shift its funding away from primate experiments by 2030.

Dutch lawmakers have approved the phase-out of primate research at one of Europe’s biggest facilities. Neuroscientists are worried.

Basket cells, parvalbumin expressing or fast-spiking neurons, names that emphasize different properties of the same type. However they are not all the same, like these in the mouse barrel cortex: one has axon in its layer; the other sends axon to other layers
Both are very beautiful

The sodium-potassium pump is a protein in the neuron's membrane that uses ATP to move three sodium ions out and two potassium ions into the cell, thereby restoring the resting potential necessary for nerve impulses.

Feature selectivity of corticocortical feedback along the primate dorsal visual pathway | Journal of Neurophysiology | American Physiological Society Anatomical studies have revealed a prominent role for feedback projections in the primate visual cortex. Theoretical models suggest that these projections support important brain functions such as att...

Synaptic alterations in pyramidal cells following genetic manipulation of neuronal excitability in monkey prefrontal cortex | Journal of Neurophysiology | American Physiological Society The primate dorsolateral prefrontal cortex (DLPFC) displays unique in vivo activity patterns, but how in vivo activity regulates DLPFC pyramidal neuron (PN) properties remains unclear. We assessed the effects of in vivo Kir2.1 overexpression, a genetic silencing tool, on synapses in monkey DLPFC PNs. We show for the first time that recombinant ion channel expression successfully modifies the excitability of primate cortex neurons, producing effects on synaptic properties apparently different from those in the rodent cortex.

Please don't send me email after email telling me my review is late. If it was that important to you, you would have asked someone else.

I saw a young man hurrying down the street today. I stopped him and said "Relax! You're young! You have all the time in the world!" He gave me a weird look. It's too bad he missed his bus. I guess that's what happens when you try to rush things.

The geometry of correlated variability leads to highly suboptimal discriminative sensory coding | Journal of Neurophysiology | American Physiological Society The brain represents the world through the activity of neural populations; however, whether the computational goal of sensory coding is to support discrimination of sensory stimuli or to generate an internal model of the sensory world is unclear. Correlated variability across a neural population (noise correlations) is commonly observed experimentally, and many studies demonstrate that correlated variability improves discriminative sensory coding compared to a null model with no correlations. However, such results do not address whether correlated variability is optimal for discriminative sensory coding. If the computational goal of sensory coding is discriminative, than correlated variability should be optimized to support that goal. We assessed optimality of noise correlations for discriminative sensory coding in diverse datasets by developing two novel null models, each with a biological interpretation. Across datasets, we found that correlated variability in neural populations leads to highly suboptimal discriminative sensory coding according to both null models. Furthermore, biological constraints prevent many subsets of the neural populations from achieving optimality, and subselecting based on biological criteria leaves red discriminative coding performance suboptimal. Finally, we show that optimal subpopulations are exponentially small as the population size grows. Together, these results demonstrate that the geometry of correlated variability leads to highly suboptimal discriminative sensory coding.

Newly characterized striatal circuits add twist to ‘go/no-go’ model of movement control The two novel pathways control dopamine release in opposing ways and may link motivation and mood to action, a new study shows.

The ‘go’ and ‘no-go’ pathways in the basal ganglia are not the only pathways that control movement, as a new study reveals two additional circuits that modulate dopamine and movement.

Color and Spatial Frequency Provide Functional Signatures of Retinotopic Visual Areas Primate vision relies on retinotopically organized cortical parcels defined by representations of hemifield (upper vs lower visual field), eccentricity (fovea vs periphery), and area (V1, V2, V3, V4)....

Happy to share our new paper, just released in the Journal of Neuroscience!

Here we use a novel tool to discover new interactions between color, spatial frequency, eccentricity, and visual area in macaque monkey fMRI data.
