Frontotemporal dementia (FTD), otherwise known as Pick’s disease, is a clinically heterogeneous group of sporadic and familial neurodegenerative diseases. These conditions are characterized by dementia, behavioural and language dysfunction and loss of executive skills resulting from the degeneration of the frontal and temporal lobes. Although reversible causes of dementia are always sought during the evaluation of patients with progressive cognitive decline, the occurrence of a reversible aetiology may distract from evaluating for neurodegenerative causes of dementia. This report is about a 66-year old man with features of FTD and superimposed chronic subdural haematoma.
Acetylcholine Release In Mouse Hippocampal Ca1 Preferentially Activates Inhibitory-Selective Interneurons Via Α4Β2* Nicotinic Receptor Activation, L. Andrew Bell, Karen A. Bell, A. Rory Mcquiston
Acetylcholine Release In Mouse Hippocampal Ca1 Preferentially Activates Inhibitory-Selective Interneurons Via Α4Β2* Nicotinic Receptor Activation, L. Andrew Bell, Karen A. Bell, A. Rory Mcquiston

Acetylcholine (ACh) release onto nicotinic receptors directly activates subsets of inhibitory interneurons in hippocampal CA1. However, the specific interneurons activated and their effect on the hippocampal network is not completely understood. Therefore, we investigated subsets of hippocampal CA1 interneurons that respond to ACh release through the activation of nicotinic receptors and the potential downstream effects this may have on hippocampal CA1 network function. ACh was optogenetically released in mouse hippocampal slices by expressing the excitatory optogenetic protein oChIEF-tdTomato in medial septum/diagonal band of Broca cholinergic neurons using Cre recombinase-dependent adeno-associated viral mediated transfection. The actions of optogenetically released ACh were …

Rationale: Cigarette smoking has been linked to a number of personality characteristics, including impulsivity. Smokers tend to endorse high levels of impulsivity, and more impulsive smokers have greater difficulty quitting, but little is known about potential explanatory mechanisms. Although indirect evidence suggests craving as a candidate mechanism, direct evidence has been mixed.
Materials and methods: This study assessed whether specific aspects of impulsivity (sensation seeking, lack of premeditation, lack of perseverance, and urgency) were associated with cue-induced craving. Regular smokers (n= 60; 50% female) were exposed to a smoking cue and a neutral cue in a repeated measure …
