One group of 12 non learning disabled students and two groups of 12 learning disabled students between the ges of 10 and 12 were measured on implicit and explicit knowledge cquisition. Students in each group implicitly cquired knowledge bout I of 2 vocabulary rules. The vocabulary rules governed the pronunciation of 2 types of pseudowords. After completing the implicit acquisition phase, all groups were administered a test of implicit knowledge. The non learning disabled group and I learning disabled group were then asked to verbalize the knowledge acquired during the initial phase. This was a test of explicit knowledge. All 3 groups were then given a postlest of implicit knowledge. This tcst was a measure of the effectiveness of the employment of the verbalization technique. Results indicate that implicit knowledge capabilities for both the learning disabled and non learning disabled groups were intact. However. there were significant differences between groups on explicit knowledge capabilities. This led to the conclusion that implicit functions show little individual differences, and that explicit functions are affected by ability difference. Furthermore, the employment of the verbalization technique significantly increased POStlest scores for learning disabled students. This suggested that the use of metacognitive techniques was a beneficial learning tool for learning disabled students.

Intracerebroventricular (ICV) administration of bombesin (BN) induces a
syndrome characterized by stereotypic locomotion and grooming,
hyperactivity and sleep elimination, hyperglycemia and hypothermia,
hyperhemodynamics, feeding inhibition, and gastrointestinal function
changes. Mammalian BN-like peptides (MBNs), e.g. gastrin-releasing
peptide (GRP), Neuromedin C (NMC), and Neuromedin B (NMB), have been
detected in the central nervous system. Radio-labeled BN binds to specific
sites in discrete cerebral regions. Two specific BN receptor subtypes (GRP
receptor and NMB receptor) have been identified in numerous brain regions.
The quantitative 2-[14C]deoxyglucose ([14C]20G) autoradiographic
method was used to map local cerebral glucose utilization (LCGU) in the
rat brain following ICV injection of BN (vehicle, BN O.1Jlg, O.5Jlg). At each
dose, experiments were conducted in freely moving or restrained
conditions to determine whether alterations in cerebral function were the
result of BN central administration, or were the result of BN-induced
motor stereotypy. The anteroventral thalamic nucleus (AV) (p=O.029),
especially its ventrolateral portion (AVVL) (p
