Multireceptor fingerprints in progressive supranuclear palsy.
ddc:610
Progressive supranuclear palsy (PSP) with a frontal presentation, characterized by cognitive deficits and behavioral changes, has been recognized as an early clinical picture, distinct from the classical so-called Richardson and parkinsonism presentations. The midcingulate cortex is associated with executive and attention tasks and has consistently been found to be impaired in imaging studies of patients with PSP. [...]

Genetic effects influencing risk for major depressive disorder in China and Europe
ddc:610
Major depressive disorder (MDD) is a common, complex psychiatric disorder and a leading cause of disability worldwide. Despite twin studies indicating its modest heritability (~30–40%), extensive heterogeneity and a complex genetic architecture have complicated efforts to detect associated genetic risk variants. [...]

Directional spread of activity in synaptic networks of the human lateral amygdala.
ddc:610
Spontaneous epileptiform activity has previously been observed in lateral amygdala (LA) slices derived from patients with intractable-temporal lobe epilepsy. The present study aimed to characterize intranuclear LA synaptic connectivity and to test the hypothesis that differences in the spread of flow of neuronal activity may relate to spontaneous epileptiform activity occurrence. [...]

Functional reorganization in obstructive sleep apnoea and insomnia: A systematic review of the resting-state fMRI.
ddc:150
Functional neuroimaging techniques have accelerated progress in the study of sleep disorders. Considering the striking prevalence of these disorders in the general population, however, as well as their strong bidirectional relationship with major neuropsychiatric disorders, including major depressive disorder, their numbers are still surprisingly low.

Synaptic patterning and the timescales of cortical dynamics.
ddc:610
Neocortical circuits, as large heterogeneous recurrent networks, can potentially operate and process signals at multiple timescales, but appear to be differentially tuned to operate within certain temporal receptive windows. The modular and hierarchical organization of this selectivity mirrors anatomical and physiological relations throughout the cortex and is likely determined by the regional electrochemical composition.

D2 : localized modes at extended defects in crystals
[Juel-0319-RW]
Berichte der Kernforschungsanlage Jülich 319, p. 439-50 (1964)
Perturbations in the homogeneity of a crystal can give rise to localized modes of vibration. We have discussed the simplest cases of extended defects, namely planes of impurity atoms with special directions (001, 011, etc.) in a simple cubic crystal with nearest neighbour interaction [...]

Temperaturen abgebrannter Brennstoffelemente des Reaktors FRJ-2 ausserhalb des Reaktors
[Juel-0316-RE]
Berichte der Kernforschungsanlage Jülich 316, 44 p. (1965)
Im vorliegenden Bericht wurden die Temperaturen abgebrannter Brennstoffelemente (Typ Mk IIc) des Reaktors FRJ-2 (DIDO), dieaußerhalb des Reaktors in einem Absetzblock mit Gas gekühlt werden, berechnet. Dabei wurden zwei Fälle behandelt a) Kühlung bei erzwungener Strömung des Kühlgases b) Kühlung bei freier Strömung des Kühlgases [...]
