Neuroanatomical correlates of human reasoning.
May 1, 1998... INTRODUCTION Reasoning is the process of evaluating given information and reaching conclusions that are not explicitly stated. Here is literature's most celebrated reasoner (Conan Doyle's Sherlock Holmes in Scandal in Bohemia) impressing his...

A functional neuroimaging description of two deep dyslexic patients.
May 1, 1998... INTRODUCTION Deep dyslexia is one of the most prominent of all known neuropsychological syndromes. It played an important role in sparking the development of cognitive neuropsychology (Marshall & Newcombe, 1973), and over the last two decades,...

Coupled temporal memories in Parkinson's disease: a dopamine-related dysfunction.
May 1, 1998... INTRODUCTION Patients with Parkinson's disease (PD) experience difficulties when producing temporal components of movement and in programming and synchronizing motor responses. These problems are reflected in increased reaction time and...

Perseveration and strategy in a novel spatial self-ordered sequencing task for nonhuman primates: effects of excitotoxic lesions and dopamine depletions of prefrontal cortex.
May 1, 1998... INTRODUCTION Damage to prefrontal cortex results in impaired performance on a variety of self-ordered sequencing tasks, while leaving more general mnemonic abilities intact. Thus, clinical studies have consistently demonstrated that patients...

Is the category-specific deficit for living things spurious?
May 1, 1998... INTRODUCTION Some brain-damaged patients encounter more difficulty recognizing living things, including animals and plants, than nonliving things. Warrington and Shallice (1984) first documented this phenomenon in four patients who had...

Semantic and visual determinants of face recognition in a prosopagnosic patient.
May 1, 1998... INTRODUCTION Prosopagnosia is the ncuropathological inability to recognize familiar people by their faces. The temporal lobe patient ELM, for example, is unable to recognize the faces of his wife, sons, or grandchildren. He claimed a picture...

H.M. revisited: relations between language comprehension, memory, and the hippocampal system.
May 1, 1998... INTRODUCTION In 1953, a "frankly experimental operation" removed parts of the hippocampal system of a 27-year-old patient known as H.M. (Scoville & Milner, 1957). This bilateral operation partially alleviated H.M.'s debilitating and otherwise...

Deficits in complex visual perception following unilateral temporal lobectomy.
May 1, 1998... INTRODUCTION The role of the human temporal cortex in simple visual perception is at present unclear. There are many indications from physiological (Desimone, Albright, Gross, & Bruce, 1984; Desimone & Gross, 1979; Gross, Bender, & Gerstein,...

Semantic processing of spoken words in Alzheimer's disease: an electrophysiological study.
May 1, 1998... INTRODUCTION One of the principal cognitive deficits associated with AD is the impaired performance of AD patients in a variety of semantic tasks. The patients have difficulties in word finding (poverty of content words in spontaneous speech,...

Auxiliary selection in Italian: a comment on Miozzo and Caramazza's "On knowing the auxiliary of a verb that cannot be named: evidence for the independence of grammatical and phonological aspects of lexical knowledge". (reply to M. Miozzo et.al., Journal of Cognitive Neuroscience, vol. 9, no. 1, p. 160, 1997)
May 1, 1998... In a paper published in the 9:1 issue of the Journal of Cognitive Neuroscience, Miozzo and Caramazza report the case of an anomic Italian patient (Dante) who is able to retrieve a verb's auxiliary despite being unable to retrieve the verb's...
