Auditory Short-Term Memory Behaves Like Visual Short-Term Memory Timing and Sequence of Brain Activity in Top-Down Control of Visual-Spatial Attention An Unexpected Sequence of Events: Mismatch Detection in the Human Hippocampus —–—2006 How Behavioral Constraints May Determine Optimal Sensory Representations -- The sensory-triggered activity of a neuron is typically characterized in terms of a tuning curve, which describes the neuron's average response as a function of a parameter that characterizes a physical stimulus . . . the main idea being that sensory neurons should represent the sensory world as accurately and efficiently as possible . . . the efficient coding hypothesis, has been extremely successful at predicting the receptive field properties of neurons in early visual and auditory areas, and it is consistent with numerous experimental observations Functional Convergence of Neurons Generated in the Developing and Adult Hippocampus -- The dentate gyrus (DG) of the adult hippocampus contains neural progenitor cells that divide, differentiate, and migrate to produce functional neurons that become incorporated into the existing hippocampal circuitry. Rapid Redistribution of Synaptic PSD-95 in the Neocortex In Vivo -- Most excitatory synapses terminate on dendritic spines, tiny membrane protrusions that contain the postsynaptic density (PSD). Spines vary in size, and their volumes are proportional to the area of the PSD and synaptic strength. The PSD is a proteinaceous complex composed of receptors, adhesion molecules, and signaling complexes. Implicit Multisensory Associations Influence Voice Recognition Generalization of Motor Learning Depends on the History of Prior Action -- results are supported by a single Bayesian model of motor learning in which generalization depends on the history of prior motor behavior. Dorsoventral Patterning in Hemichordates: Insights into Early Chordate Evolution Unique Development in Hemichordates Suggests Some Unique Features of Chordates Your Synapse or Mine? Promiscuous Protein Exchanges between Neighboring Synapses – Synapses can be plastic or stable in the mammalian brain. Whereas some plasticity remains and allows for learning, most synapses stabilize, and some may last a lifetime. How synapses are maintained over long periods is a mystery, especially since structural proteins constantly move in and out of synapses. Two prominent synaptic proteins, Synapsin I and ProSAP2, turn over primarily through rapid exchanges between neighboring synapses. Is Avoiding an Aversive Outcome Rewarding? Neural Substrates of Avoidance Learning in the Human Brain Dynamics of the Central Bottleneck: Dual-Task and Task Uncertainty — Several cognitive theories share the hypothesis that while most mental and neural operations are modular, certain controlled processes require a distinct capacity-limited “central executive” or “global workspace” system that can establish flexible links among existing processors.

Theta Rhythms Coordinate Hippocampal–Prefrontal Interactions in a Spatial Memory Task Cortical Sensitivity to Visual Features in Natural Scenes -- A central hypothesis concerning sensory processing is that the neuronal circuits are specifically adapted to represent natural stimuli efficiently.
