Retinal Circuitry and Vision
The daunting, yet fascinating complexity of the central nervous system, embodied by diverse cell types, circuits, parallel pathways and neural computations is beautifully embodied in the neural retina at the start of the visual process. The retina comprises on the order of 100 cell types; these cell types create functionally diverse circuits that give rise to, by one recent estimate, from 30-50 parallel pathways to the brain’s visual processing structures. Our long-term goal has been to advance understanding of the origins of these pathways in the retina and the underlying neural mechanisms that can create both color coding circuits and motion sensitive direction selective circuits from the same basic neural substrate. The non-human primate provides a perfect model for the human retina, distinguished from other mammals by its specialized foveal structure and trichromatic color code; we developed the first in vitro preparation of the macaque monkey retina that permitted the first targeting of primate retinal circuits with single cell intracellular physiology.
Today our research program is focused on two parallel tracks. First, we have identified for the first time in the primate the key cell types and circuits that encode the direction of visual motion. To probe all aspects of this circuitry we are utilizing novel visual stimuli, 2-photon calcium imaging of dendritic signals, the voltage clamp to measure light-evoked synaptic currents, electron microscopic reconstruction to identify critical synaptic motifs and finally computation and compartmental modeling of biologically realistic circuits.
Second, to complement our physiological studies in the in vitro macaque retina we have joined an exciting a team of clinicians and histopathologists to apply new methods of ‘volume’ electron microscopy – connectomics – to reconstruct the complete circuitry of the human fovea for the first time. Our approach combines recent advances in electron microscopy, handling big datasets, and artificial intelligence approaches to automate interrogation of complex circuits. An exciting element of this line of investigation is that we are including non-neuronal-neuronal cell interactions that are critical to understanding cellular changes that occur in blinding retinal diseases that attack the human fovea.
My interest in neuroscience probably traces back to reading Freud’s, “The Interpretation of Dreams” the long hot summer before I started high school spending a lot of time in bed scribbling down my dreams and sorting out the “latent” from the “manifest” content of my teenage dreams! I got into wrestling (a great sport) and became obsessed with the concept of “satiety” which naturally led to a senior thesis in 1976 on the role of the hypothalamus in food intake…which of course we still don’t understand though advances have been made.
I ended up in the lab of Sebastian Grossman at the University of Chicago making lesions in various locations in the rat’s amygdala and hypothalamus and measuring changes in, of course, satiety! It was not long before I became fed up with making holes in the brain and discovered comparative neurobiology and fantastically complex neural circuits, like the “jamming-avoidance response” of electric fish.I left rats behind and begged my way into the lab of Phil Ulinski where the lab mascot was a Greek tortoise named Clyde and we worked on the brains of turtles and snakes with a goal towards understanding homologies between reptilian and mammalian brains. Like any neuro-kid Cajal wannabe I became obsessed with circuits and the myriad diversity of neural cell types in the deluge of vertebrate neural systems available for study. I forgot all about evolution and my thesis could be called “everything you wanted to know about the cell types of the optic tectum of a garden snake….”
Chicago was a hard place to live, with record cold and snow every winter it seemed so when the Australian neuroscientist Jonathan Stone came for a visit the prospect of a postdoc in Sunny Sydney was enticing! I wanted to work on the emerging complexity of multiple visual areas in neocortex but something was lost in translation and I ended up trying to figure out the retinal ganglion cell types of the cat’s retina. Cat’s were in plentiful supply in Sydney since wild ones were considered a terrible pest that devoured all those cute marsupials. It was tough going getting to know the retina, especially with beautiful beaches within walking distance from the lab. However enough data was gathered and with some good luck was able to get my first NIH grant in 1985 to study cat retinal ganglion cells.
The rest is history as they say. I was lucky enough to later meet up with great retinal neurobiologists and vision scientists like Bob Rodieck (who introduced me to the primate retina), Christine Curcio (my officemate!), John Troy, Joel Pokorny, Vivianne Smith, Barry Lee, David Williams, Dave Brainard and Julie Schnapf and Peter Detwiler who taught me so much about vision, the retina and doing research and having fun. Right now the lab is focused on working out the circuitry for direction selectivity (with Peter Detwiler and John Troy) an old problem, but a new one for the primate retina and applying the new methods of “connectomics” to characterizing the foveal microcircuits in the human retina in collaboration (with Christine Curcio).
SPOTLIGHT
S-cone circuitry in non-human primate and human retina
The short wavelength-sensitive (S) cones comprise less than 10% of the cone photoreceptors in the primate retina and investigation of their specialized role in color vision has a long history. Our first encounter with this distinctive pathway came with the discovery in the 1990's of a novel ganglion cell type that transmitted a 'blue-yellow' color signal to the brain. Since then we have continued to study many features of this neural circuit, including the physiology of the S-cone themselves, interneurons linked to the S-cone as well as other S-cone related color coding visual pathways. Currently we are using the connectomics approach to characterize new features of the S-cone circuitry in the human retina and calcium imaging of dendritic processing in the macaque retina to better understand how color opponency originates in this fascinating visual pathway.
