- The cholecystokinin tetrapeptide (CCK-4) and the sulphated octapeptide (CCK-8) were measured in cerebrospinal fluid obtained from nine hypothyroid patients before and during L-thyroxine treatment. Before treatment, CCK-4 and CCK-8S correlated negatively with S-TSH, whereas CCK-8S also showed a positive correlation with S-T3. During treatment, S-T4 correlated negatively with CCK-8S. CSF collection time was significantly shorter during treatment than prior to treatment for the first (0–6 ml) CSF fraction. On taking CSF collection time into account, the levels of both CCK-4 and CCK-8S in the first CSF fraction were significantly increased during medication. Our results are consistent with an impact of the hypothyroid disorder and L-thyroxine treatment on the disposition of CCK compounds in CSF. This might be due to an altered CSF circulation, but other mechanisms (e.g. metabolism or elimination) cannot be ruled out.

Directed forgetting, event-related potentials and nicotine

- Fifteen male users of oral snuff performed a directed forgetting task after over-night abstinence and after administration of oral snuff. Directed forgetting tasks use cues to classify items for differential reporting at test, emphasising the need for strategic encoding. Recognition was better after nicotine administration, but we found no evidence for greater strategic control, as hypothetically reflected in successful compliance with the directed forgetting instructions. Reaction time decreased after nicotine administration. Performance among fifteen controls was unaffected over two sessions.

Effects of nicotine in visual attention tasks

- Thirty-five male volunteers (18 nicotine-users and 17 controls) participated in an experiment where a flanker task and a search task were used. It was hypothesized that if nicotine affects selective attention, effects of distracting flanker stimuli should be diminished, and effects of allocation strategies in the search task should be more marked. Nicotine-users performed the tasks after an over-night abstinence, and after administration of oral snuff. In both tasks nicotine users improved more than controls, but there was no indication of nicotine effects on selective attention in either task. Our results point towards a non-specific arousing effect of nicotine.
