t encapsulated some dendritic spines. Astrocytic processes extended and retracted considerable distances (5 m) during a 30 min observation period. The GABAA receptor antagonist bicuculline, which increases neural activity, stabilized spines but had no apparent effect on astrocyte motility. In general, interactions between astrocyte processes and larger spines were more stable than those with smaller spines.

3. To Burst or Not to Burst in the Medial Septum In Vivo

The neurons in the medial septumdiagonal band of Broca (MS-DB) have long been implicated in hippocampal theta rhythms. In this week's Journal, Simon et al. sought to differentiate the firing patterns of GABAergic and cholinergic MS-DB neurons. Their results indicate that GABAergic cells rather than cholinergic neurons display theta-related bursting or tonic activity in the MS-DB. Parvalbumin (PV) labels most GABAergic septohippocampal neurons, whereas other GABAergic neurons express glutamic acid decarboxylase (GAD). The authors recorded from MS-DB neurons in anesthetized and unanesthetized rats, and labeled the recorded neurons with neurobiotin. Of 90 neurons, three-quarters expressed GAD, and PV labeled approximately one-third of those. Only eight neurons, negative for GAD and PV, were cholinergic. GABAergic neurons displayed tonic, cluster, or burst-firing discharge patterns that varied with the sleepCwake cycle, but PV-positive neurons displayed more pronounced rhythmic bursting activity. Cholinergic neurons all displayed a low discharge rate.
