Computational Modeling of Receptive Field Construction in Midget Ganglion Cells of Primate Retina

Computational Modeling Study on the Construction of Receptive Fields in Midget Ganglion Cells of Primate Retina Academic Background The midget pathway in the primate retina is the foundation for high spatial resolution and color perception in the visual system. A key feature of this pathway is the center-surround organization of the receptive field...

The Geometry of Correlated Variability Leads to Highly Suboptimal Discriminative Sensory Coding

Correlated Variability in the Brain Leads to Highly Suboptimal Sensory Coding Academic Background The brain perceives the world through the activity of neural populations, but it remains unclear whether the computational goal of sensory coding is to support the discrimination of sensory stimuli or to generate an internal model of the sensory world....

Dopamine Receptors D1, D2, and D4 Modulate Electrical Synapses and Excitability in the Thalamic Reticular Nucleus

The Regulatory Role of Dopamine Receptors in the Thalamic Reticular Nucleus: A Study on Neuronal Excitability and Electrical Synapses Academic Background The Thalamic Reticular Nucleus (TRN) is a crucial inhibitory neuronal network in the brain, responsible for regulating the transmission of sensory information between the thalamus and the cortex. ...

Chilean Brush-Tailed Mouse (Octodon degus): A Diurnal Precocial Rodent as a New Model to Study Visual Receptive Field Properties of Superior Colliculus Neurons

The Chilean Brush-tailed Mouse (Octodon degus) as a New Model for Studying the Visual System Academic Background The study of the visual system has always been an important topic in the field of neuroscience. Traditionally, scientists have used nocturnal or crepuscular rodents (such as hamsters, rats, and mice) as models to study the development an...

Estimating Descending Activation Patterns from EMG in Fast and Slow Movements Using a Model of the Stretch Reflex

Estimating Descending Activation Patterns from EMG in Fast and Slow Movements Using a Stretch Reflex Model Background In the field of motor control, descending activation from the brain is the primary source of muscle activation, but spinal reflex loops also play a significant role in movement generation. The spinal stretch reflex is a short-latenc...
