The 28th American Society for Neural Therapy and Repair (ASNTR) returned to the Sheraton Sand Key in Clearwater Beach, Florida after an 18 month hiatus. Like nearly all conferences during the pandemic, the ASNTR conference was held in person while offering a virtual option to the event. These formats are advantageous for those under travel restrictions or personal constraints, but they lack the spontaneity of in-person connections. Highlights from the meeting included the return of the Bernard Sanberg Memorial Award and the Roy Bakay Memorial lecture. The presidential lecture was given by Gabriel de Erausquin, who discussed the possibility of long-term CNS effects resulting from SARS-CoV2 infection. With both virtual and in-person events, including oral and poster presentations, the ASNTR managed to maintain the unique essence of this small important meeting.

Modern accounts of visual motion processing in the primate brain emphasize a hierarchy of different regions within the dorsal visual pathway, especially primary visual cortex (V1) and the middle temporal area (MT). However, recent studies have called the idea of a processing pipeline with fixed contributions to motion perception from each area into doubt. Instead, the role that each area plays appears to depend on properties of the stimulus as well as perceptual history. We propose to test this hypothesis in human subjects by comparing motion perception of two commonly used stimulus types: drifting sinusoidal gratings (DSGs) and random dot patterns (RDPs). To avoid potential biases in our approach we are pre-registering our study. We will compare the effects of size and contrast levels on the perception of the direction of motion for DSGs and RDPs. In addition, based on intriguing results in a pilot study, we will also explore the effects of a post-stimulus mask. Our approach will offer valuable insights into how motion is processed by the visual system and guide further behavioral and neurophysiological research.

Recent research resolves the challenging problem of building biophysically plausible spiking neural models that are also capable of complex information processing. This advance creates new opportunities in neuroscience and neuromorphic engineering, which we discussed at an online focus meeting.
