Estimating a State-Space Model from Point Process Observations
We develop an approximate expectation-maximization (EM) algorithm to estimate the unobservable state-space model observed through point process measurements. Expand
Dynamic Analysis of Learning in Behavioral Experiments
We develop a state-space model paradigm to characterize learning as the probability of a correct response as a function of trial number (learning curve). Expand
Single Neurons in the Monkey Hippocampus and Learning of New Associations
The medial temporal lobe is crucial for the ability to learn and retain new declarative memories. This form of memory includes the ability to quickly establish novel associations between unrelatedExpand
An international field study of the reliability and validity of a disease-specific questionnaire module (the QLQ-MY20) in assessing the quality of life of patients with multiple myeloma.
AIM To test the reliability, validity and sensitivity of the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-MY24 questionnaire, designed to assess the quality of life ofExpand
Functional Magnetic Resonance Imaging Activity during the Gradual Acquisition and Expression of Paired-Associate Memory
Recent neurophysiological findings from the monkey hippocampus showed dramatic changes in the firing rate of individual hippocampal cells as a function of learning new associations. To extend theseExpand
Intraoperative measurement of knee kinematics in reconstruction of the anterior cruciate ligament.
Our objectives were to establish the envelope of passive movement and to demonstrate the kinematic behaviour of the knee during standard clinical tests before and after reconstruction of the anteriorExpand
Probabilistic reinforcement learning in adults with autism spectrum disorders
Background: Autism spectrum disorders (ASDs) can be conceptualized as disorders of learning, however there have been few experimental studies taking this perspective. Methods: We examined theExpand
Randomized phase III study of fludarabine phosphate versus cyclophosphamide, vincristine, and prednisone in patients with recurrent low-grade non-Hodgkin's lymphoma previously treated with an
PURPOSE To compare in a phase III study the safety and efficacy of fludarabine to that of cyclophosphamide, vincristine, and prednisone (CVP) in recurrent, low-grade, non-Hodgkin's lymphoma afterExpand
Feedback-driven trial-by-trial learning in autism spectrum disorders.
OBJECTIVE Impairments in learning are central to autism spectrum disorders. The authors investigated the cognitive and neural basis of these deficits in young adults with autism spectrum disordersExpand
A Bayesian statistical analysis of behavioral facilitation associated with deep brain stimulation
Deep brain stimulation (DBS) is an established therapy for Parkinson's Disease and is being investigated as a treatment for chronic depression, obsessive compulsive disorder and for facilitatingExpand
