properly cited.We recall the life and work of Timothy J. Crow, whose contributions provided great insights into the pathophysiology of schizophrenia and continue to shape many questions in the field. We compile his key works relating to psychotic disorders, focusing on the trajectory of his theoretical stance. Our account is interlaced with our own interpretation of the evidence that influenced Crow's arguments over the years as well as his scientific method. Crow has had a significant impact on the neuroscience of schizophrenia. Many of his observations are still valid and several questions he raised remain unanswered to date.https://www.cambridge.org/core/journals/psychological-medicine/article/seminal-contributions-of-timothy-j-crow/25B0EA70F496D0D3351937E44ADDD45
The functional roles of prefrontal cortex in episodic memory. II Retrieval
No full textFunctional neuroimaging studies of memory retrieval show consistent activation of the right prefrontal and superior parietal cortex. We examined the specific role of the prefrontal cortex during retrieval with the hypothesis that this region mediates monitoring processes necessary for optimal recall. During functional neuroimaging with PET, subjects retrieved verbal material under two conditions. In the first, an organizational structure had been provided, prior to scanning, and this formed the basis for a monitored memory search while the scan took place. A comparison condition did not require a monitored search because recall was externally cued. In both conditions, when compared with baseline tasks prefrontal cortex and medial parietal activation was observed. Within the right prefrontal cortex activation an anatomical dissociation was seen between the dorsal and ventral prefrontal cortex. The dorsal region showed greater activation when monitoring demands were emphasized, while the ventral region showed greater activation when external cueing was emphasized. An unpredicted dissociation within the superior parietal activation was also observed, a dorsal region showing activation during the monitored search task and a more ventral region showing activation under the externally cued condition. The results provide evidence for functional specialization of the right prefrontal cortex For discrete cognitive processes during episodic memory retrieval

Brain regions associated with the acquisition and retrieval of verbal episodic memory
No full textIT is widely held that conscious recall of past experiences involves a specific system-episodic memory1. Patients with amnesia have gross impairments of episodic memory while other kinds of memory remain intact2,3, suggesting that a separable brain system underlies episodic memory. We have used positron emission tomography (PET) to identify components of this system in normal volunteers. A dual-task interference paradigm4 was used to isolate brain areas associated with acquisition, and a cueing paradigm5 to isolate the areas concerned with retrieval from verbal episodic memory. Acquisition was associated with activity in the left prefrontal cortex and the retrosplenial area, whereas retrieval was associated with activity in right prefrontal cortex and the precuneus. Our results provide clear evidence that episodic memory involves a network of specific prefrontal and posterior structures6,7 which can be fractionated into different component processes

At Brief History of the Sherlock Holmes Collections at the University of Minnesota
No full textProvides a brief history on the origins of the Sherlock Holmes Collections, a unit within the Department of Archives and Special Collections for the University of Minnesota Libraries. The article traces the history of the Collections from the initial purchase in 1974 of the James Iraldi collection--the beginning of the Collections--through the 1990s. The acquisition of additional collections over those three decades resulted in the world's largest gathering of material related to Mr. Sherlock Holmes and his author, Sir Arthur Conan Doyle.Johnson, Timothy J.
