OBJECT The purpose of this paper was to describe the clinical outcome in patients with brain metastases who underwent gamma knife radiosurgery (GKS). METHODS The authors retrospectively reviewed the clinical courses of 54 patients with brain metastases who underwent 62 GKS procedures. This series covered a 43-month period. A total of 174 lesions were(More)
Septohippocampal interactions determine how stimuli are encoded during conditioning. This study extends a previous neurocomputational model of corticohippocampal processing to incorporate hippocamposeptal feedback and examines how the presence or absence of such feedback affects learning in the model. The effects of septal modulation in conditioning were(More)
Recent evidence suggests that (a) auditory cortical neurons are tuned to complex time-varying acoustic features, (b) auditory cortex consists of several "elds that decompose sounds in parallel, (c) the metric for such decomposition varies across species, and (d) auditory cortical representations can be rapidly modulated. Past computational models of(More)
Extensive practice on auditory learning tasks dramatically alters the functional organization and response properties of neurons in the auditory cortex. The cellular mechanisms responsible for this auditory learning-induced cortical plasticity are unclear; however, changes in synaptic function involving NMDA receptors have been strongly implicated. To test(More)
The common assumption that perceptual sensitivities are related to neural representations of sensory stimuli has seldom been directly demonstrated. The authors analyzed the similarity of spike trains evoked by complex sounds in the rat auditory cortex and related cortical responses to performance in an auditory task. Rats initially learned to identify 2(More)
A commentary on Interpretations without justification: a general argument against Morgan's Canon by Starzak, T. (2016). Synthese. Morgan's Canon has been touted as " the most awesome weapon in animal psychology, " (Wynne and Udell, 2013, p. 14). The enemies that this century-old principle is usually employed to destroy are explanations of behavior that(More)
Course Overview This course surveys selected topics in modern cognitive psychology with an emphasis on learning and memory. It is intended for undergraduate students with basic knowledge of psychology and statistics (prerequisites Psych 100 and Psych 220 or equivalent). Some questions we will consider are: What is cognitive psychology? What methods do(More)
A fundamental assumption of current hypotheses regarding hippocampal involvement in memory formation is that changes in synaptic connections between hippocampal neurons serve to encode information about recent events. An alternative possibility is that synaptic changes are " ruts " left by dynamic traveling waves involved in memory processes rather than a(More)
