Mechanisms of amyloid plaque pathogenesisJohn C Fiala
Department of Health Sciences, Boston University, Boston, MA 02215, USA
Acta Neuropathol 114:551-71. 2007..The theory of amyloid plaque pathogenesis has thus come full circle, back to the intuitions of the very first researchers in the field...
Mitochondrial degeneration in dystrophic neurites of senile plaques may lead to extracellular deposition of fine filamentsJohn C Fiala
Department of Health Sciences, Boston University, 635 Commonwealth Ave, Boston, MA 02215, USA
Brain Struct Funct 212:195-207. 2007..This progression of degeneration suggests that extracellular filaments originate inside degenerating mitochondria of neuritic diverticula, which may be a common process in diverse diseases...
Reconstruct: a free editor for serial section microscopyJ C Fiala
Department of Biology, Boston University, Boston, MA, USA
J Microsc 218:52-61. 2005..As a flexible editor, Reconstruct can reduce the time and resources expended for serial section studies and allows a larger tissue volume to be analysed more quickly...
Dendritic spine pathology: cause or consequence of neurological disorders?John C Fiala
Department of Biology, Boston University, 5 Cummington Street, MA 02215, USA
Brain Res Brain Res Rev 39:29-54. 2002..More detailed studies are needed to determine the cause of spine pathology in most disorders and relationship between spine pathology and cognitive deficits...
Polyribosomes redistribute from dendritic shafts into spines with enlarged synapses during LTP in developing rat hippocampal slicesLinnaea E Ostroff
Biology Department, Program in Neuroscience, Boston University, 5 Cummington Street, Boston, MA 02215, USA
Neuron 35:535-45. 2002..Furthermore, coincident polyribosomes and synapse enlargement might indicate spines that are expressing long-term potentiation induced by tetanic stimulation...
Timing of neuronal and glial ultrastructure disruption during brain slice preparation and recovery in vitroJohn C Fiala
Department of Biology, Boston University, Boston, Massachusetts 02215, USA
J Comp Neurol 465:90-103. 2003..Submersing these slices in normal oxygenated media at 34 degrees C led to glycogen depletion, as well as increased coated vesicles and microtubule disassembly within 1 minute...
Dendritic spines do not split during hippocampal LTP or maturationJohn C Fiala
Biology Department, Program in Neuroscience, Boston University, 5 Cummington St, Boston, Massachusetts 02215, USA
Nat Neurosci 5:297-8. 2002
Extending unbiased stereology of brain ultrastructure to three-dimensional volumesJ C Fiala
Boston University, Boston, MA 02215, USA
J Am Med Inform Assoc 8:1-16. 2001..This paper introduces a new reconstruction system and new methods for analyzing in three dimensions the location and ultrastructure of neuronal components, such as synapses, which are distributed non-randomly throughout the brain...
Endosomal compartments serve multiple hippocampal dendritic spines from a widespread rather than a local store of recycling membraneJames R Cooney
Department of Biology, Boston University, Boston, Massachusetts 02215, USA
J Neurosci 22:2215-24. 2002..Small vesicles did not colocalize in spines with endosomes or SER. Three-dimensional reconstructions revealed that up to 20 spines shared a recycling pool of plasmalemmal proteins rather than maintaining independent stores at each spine...
Cylindrical diameters method for calibrating section thickness in serial electron microscopyJ C Fiala
Department of Biology and Program in Neuroscience, 5 Cummington St, Boston University, Boston MA 02215, USA
J Microsc 202:468-72. 2001..The cylindrical diameters method gives the same answer as that obtained by the minimal folds METHOD: It is preferable because it can be done in a series that has no folds that can distort and obscure the objects that are being measured...
Structural changes at dendritic spine synapses during long-term potentiationKristen M Harris
Synapses and Cell Signaling Program, Medical College of Georgia, Institute of Molecular Medicine and Genetics, 1120 15th Street, CB 2803, Augusta, GA 30912 2630, USA
Philos Trans R Soc Lond B Biol Sci 358:745-8. 2003..Thus, both enhanced connectivity and enlarged synapses result during LTP, with synapse enlargement being the greater effect...
