13. Ontogeny of synaptic phosphoproteins in brain.
The ontogeny of two endogenous substrates for cyclic AMP-dependent protein kinase (ATP:protein phosphotransferase; EC 2.7.1.37) has been studied in rat and guinea pig cerebrum. These endogenous substrates, referred to as proteins Ia and Ib, have been shown in other studies to be specific to nervous tissue and to be enriched in the synaptic membrane and synap

18. Gyrus formation in the cerebral cortex in the ferret. I. Description of the external changes.
The external features of gyrus formation in the postnatal ferret cerebral cortex are described and correlated with certain internal changes. The observations indicate that gyri are formed by longitudinal and radial expansion of the cortical compartment occurring between relatively fixed areas which form the sulcal floors. The gyri were initially rounded with

19. Maturational Patterns of Iodothyronine Phenolic and Tyrosyl Ring Deiodinase Activities in Rat Cerebrum, Cerebellum, and Hypothalamus
To explore the control of thyroid hormone metabolism in brain during maturation, we have measured iodothyronine deiodination in homogenates of rat cerebrum, cerebellum, and hypothalamus from 1 d postnatally through adulthood. Homogenates were incubated with 125I-l-thyroxine (T4) + [131I]3,5,3′-l-triiodothyronine (T3) + 100 mM dithiothreitol. Nonradioactive

20. Cliniconeuropathologic findings of familial frontal lobe epilepsy in Shetland sheepdogs
We examined an epileptic focus by electroencephalography (EEG) by using an international 10-20 electrode system in 11 Shetland sheep dogs affected with familial idiopathic epilepsy. We also performed an evaluation of the amino acids in the cerebrospinal fluid (CSF) and a pathologic examination of the brains of 8 dogs that died from status epilepticus. Contin

21. Labelling of amoeboid microglial cells in the supraventricular corpus callosum following the application of horseradish peroxidase in the cerebrum and spinal cord in rats.
Following an injection of horseradish peroxidase solution into the cervical or lumbosacral segments of the spinal cords, or into the parietal cortices, of postnatal (1-10 days), developing (15-20 days) and mature (2 months and older) rats, only postnatal rats demonstrated peroxidase-positive amoeboid microglial cells in the supraventricular part of the corpu

22. Tuberous sclerosis: unusual associations in four cases.
Tuberous sclerosis is a rare disease with classic primary or secondary changes affecting mainly the cerebrum, skin, kidneys, and heart. Such lesions are generally hamartomatous and thus display malignant features only in rare cases. This paper describes four cases of tuberous sclerosis which were unique in their association with certain unusual congenital, m

23. Striatal blood flow, glucose metabolism and 18F-dopa uptake: difference in Parkinson's disease and atypical parkinsonism.
Striatal blood flow, glucose metabolism and 18F-Dopa uptake were studied with positron emission tomography (PET) in eight non-demented patients with idiopathic Parkinson's disease and eight with atypical Parkinsonism. Patients with atypical Parkinsonism had no specific cause for the Parkinsonian symptoms and were clinically different from Parkinson's disease

24. Regulation of tubulin and actin mRNA production in rat brain: expression of a new beta-tubulin mRNA with development.
The expression of alpha-tubulin, beta-tubulin, and actin mRNA during rat brain development has been examined by using specific cDNA clones and in vitro translation techniques. During brain maturation (0 to 80 days postnatal), these mRNA species undergo a significant decrease in abundance. The kinetics of this decrease varies between the cerebrum and the cere
