Article Synopsis
- The text includes a collection of research topics related to neural circuits, mental disorders, and computational models in neuroscience.
- It features various studies examining the functional advantages of neural heterogeneity, propagation waves in the visual cortex, and dendritic mechanisms crucial for precise neuronal functioning.
- The research covers a range of applications, from understanding complex brain rhythms to modeling auditory processing and investigating the effects of neural regulation on behavior.

Recent research dealing with the structures of the medial temporal lobe (MTL) has shifted away from exclusively investigating memory-related processes and has repeatedly incorporated the investigation of complex visual perception. Several studies have demonstrated that higher level visual tasks can recruit structures like the hippocampus and perirhinal cortex in order to successfully perform complex visual discriminations, leading to a perceptual-mnemonic or representational view of the medial temporal lobe. The current study employed a complex visual discrimination paradigm in two patients suffering from brain lesions with differing locations and origin.

Department of Neuropsychology, Institute of Cognitive Neuroscience, Ruhr-University Bochum, Germany.
For medial temporal lobe (MTL) involvement in memory formation, it is as yet unclear whether the MTL represents a single or dual (recollection/familiarity) memory system. A further controversial issue is whether or not the hippocampus is critical for the familiarity component of recognition memory. The present prospective fMRI study aimed to investigate changes of MTL involvement in recollection and familiarity at three time points following new learning: immediately after encoding, after 3 weeks and after 6 weeks.

In the present study, we reexamined the effect of word length (number of letters in a word) on lexical decision. Using the English Lexicon Project, which is based on a large data set of over 40,481 words (Balota et al., 2002), we performed simultaneous multiple regression analyses on a selection of 33,006 English words (ranging from 3 to 13 letters in length).

Two groups of subjects, aged 20-28 and 50-64, respectively, matched for health status and verbal abilities, learned to control their slow cortical potentials (SCP) in a feedback paradigm by producing, on command, SCP shifts in either positive or negative direction. Both groups were able to differentiate significantly between the positivity task and the negativity task, with the differentiation score being only slightly (and not significantly) lower in older than in younger subjects. In all conditions, however, significantly more negative brain responses were obtained in older than in younger subjects.
