Capture-Time Perceptual Matching For More Faithful Photographs
Perceived color and lightness are ephemeral qualities dependent on many psychological factors which are difficult to measure, yet photographers often know immediately from the preview image if the captured photograph does not match their perception of the scene. However, by the time the photographer...   More >

Minimally Invasive, Wireless Neural Interfaces and Future Directions in Implantable Electronics

Seminar | March 2 | 1-2 p.m. | Soda Hall, Wozniak Lounge (430)

Rikky Muller, Cortera Neurotechnologies

Electrical Engineering and Computer Sciences (EECS)

Neural interfaces stand to revolutionize disease care for patients of neurological conditions. Electrocorticography (ECoG) is an electrophysiological technique where electrical potentials are recorded from the surface of the cerebral cortex, reducing cortical scarring. To enable chronic and stable neural recording, we have developed a miniaturized, wireless ECoG microsystem.

Talking Guinea Pigs: processing of con-specific communication calls in the cortex: Berkeley Ear Club

Colloquium | March 2 | 4-5:30 p.m. | 3105 Tolman Hall

Alan Palmer, Institute of Hearing Research, Nottingham, UK

Department of Psychology

Con-specific communication calls are vital for the survival of individuals within all species: such communication calls occur in mating and aggressive encounters and are used to signal danger. Guinea pigs are hystricomorph rodents and, like many other rodents that live in communities consisting of close-knit family groups, they produce communication calls to facilitate social interactions....   More >

V1 disparity tuning and the statistics of disparity in natural viewing

Seminar: Redwood Seminar | March 3 | 12-1:30 p.m. | 560 Evans Hall

Bill Sprague, UC Berkeley

Neuroscience Institute, Helen Wills

The efficient coding hypothesis broadly predicts that the tuning properties of neurons should reflect the statistics of the signal being encoded. For example, a sparse coding representation of natural images gives rise to receptive fields similar to those found in V1 (Olshausen and Field, 1996). A common corollary of this idea is that higher-level psychophysical phenomena can be explained by...   More >

Remembering Spatial Location: Extending the Category Adjustment Model to the Real World

Seminar: ICBS Seminar | March 6 | 11 a.m.-12:30 p.m. | 5101 Tolman Hall

Nora Newcombe, Temple University

Neuroscience Institute, Helen Wills

Initially, the Category Adjustment Model (CAM) of spatial location coding proposed by Huttenlocher, Hedges and Duncan (1991) was tested primarily with highly constrained stimuli, often the location of a dot in a circle. While these studies supported the idea of a Bayesian model of location coding, they did not address real-world coding. In this talk, I will present CAM, along with a recent series...   More >

Synaptic modulation of brain circuits controlling movement

Seminar | March 9 | 12-1 p.m. | 125 Li Ka Shing Center

Rethinking Peripheral Auditory Responses: The Neural Fluctuations that Drive the CNS: Berkeley Ear Club

Colloquium | March 9 | 4-5:30 p.m. | 3105 Tolman Hall

Laurel Carney, Biomedical Engineering, University of Rochester

Department of Psychology

Studies of the neural coding of complex sounds tend to focus on discharge rates, phase-locking to fine-structure, and how these quantities change along the auditory pathway. However, many central neurons are strongly driven by relatively low-frequency fluctuations of their inputs. This sensitivity to fluctuations is reflected in modulation transfer functions, measured using sinusoidally modulated...   More >

Sampling: a probabilistic approach to cortical computation, learning, and development

Seminar: Redwood Seminar | March 11 | 12-1:30 p.m. | 560 Evans Hall

Jozsef Fiser, Central European University

Neuroscience Institute, Helen Wills

I will present a framework and a combined empirical-computational program that explores what cortical neural representation could underlie our intelligent behavior. I will start with showing how probabilistic internal representations could be implemented in the cortex in a sampling-based manner, and how this sampling-based probabilistic approach can explain a wide range of puzzling behavioral...   More >

Echolocation in a bat cocktail party: Acoustic communication, eavesdropping and jamming avoidance: Berkeley Ear Club

Colloquium | April 6 | 4-5:30 p.m. | 3105 Tolman Hall

Cynthia Moss, Institute for Systems Research, School of Engineering, Johns Hopkins University

Department of Psychology

Echolocating bats actively probe the environment with acoustic signals and use information carried by echo returns to represent the 3-D sonar scene. Although echolocation affords insectivorous bats the distinct advantage of finding small prey at night, their reliance on active acoustic sensing also renders these animals susceptible to signal interference. Specifically, when bats forage with...   More >

Information for Perception of Speech Distorted by Sensorineural Hearing Loss: Berkeley Ear Club

Colloquium | April 13 | 4-5:30 p.m. | 3105 Tolman Hall

Josh Alexander, Speech, Language and Hearing Sciences, Purdue University

Department of Psychology

Research in my lab, the Experimental Amplification Research (EAR) lab, focuses on testing existing signal processing strategies for hearing aids as well as developing new ones. Understanding the perceptual elements of information in the speech signal and how they are affected by the interaction between signal processing strategies and hearing loss is an important first step that will help...   More >

Receptive field processing at multiple spatial scales in the auditory midbrain and forebrain: Berkeley Ear Club

Colloquium | April 20 | 4-5:30 p.m. | 3105 Tolman Hall

Craig Atensio, Center for Integrative Neuroscience, UCSF

Department of Psychology

Temporal processing becomes slower as information ascends the central auditory system. Other consistent changes have been harder to identify. We applied information-theoretic analyses to examine whether receptive field processing fundamentally changes across the auditory midbrain, thalamus, and cortex. We found that receptive fields became increasingly multidimensional from the midbrain to...   More >

Restoring spatial hearing: Cochlear implants for single-sided deafness

Restoring spatial hearing: Cochlear implants for single-sided deafness: Berkeley Ear Club

Colloquium | April 27 | 4-5:30 p.m. | 3105 Tolman Hall

Joshua Bernstein, Audiology & Speech Pathology Center, Walter Reed National Military Medical Center, Bethesda, MD

Department of Psychology

Having two ears provides tremendous advantages for listening in everyday, complex noisy environments. Differences in the arrival times or levels of sounds arriving at the two ears can relay information about where in space the sound source originates. In situations involving multiple competing sound sources, normal-hearing listeners are able to make use of differences in the signals arriving at...   More >
