Distributed and antagonistic contributions of ongoing activity fluctuations to auditory stimulus detection.

19 Oct 2009 Recent studies have shown that ongoing activity fluctuations influence trial-by-trial perception of identical stimuli. Some brain systems seem to bias toward better perceptual performance and others toward worse. We tested whether these observations ... Read more...

Receptive field organization across multiple electrosensory maps. II. Computational analysis of the effects of receptive field size on prey localization.

8 Oct 2009 The electric fish Apteronotus leptorhynchus emits a high-frequency electric organ discharge (EOD) sensed by specialized electroreceptors (P-units) distributed across the fish's skin. Objects such as prey increase the amplitude of the EOD over the ... Read more...

Strength-based criterion shifts in recognition memory.

29 Sep 2009 In manipulations of stimulus strength between lists, a more lenient signal detection criterion is more frequently applied to a weak than to a strong stimulus class. However, with randomly intermixed weak and strong test probes, such a criterion ... Read more...
