The History of the Synapse [PDF]

open access: yesThe Anatomical Record, 2020
ABSTRACTWhy did I choose this particular topic for my lecture rather than the history of neuroscience or the history of the neuron? Simply because I believe that every disciple has the obligation to pay homage to their mentors once in their lifetime. My formation as a neuroscientist involved three such mentors spanned across three countries.

Structure-function analysis on the level of individual synapses [PDF]

open access: yes, 2010
Excitatory synapses in the mammalian brain are made on small protrusions of the postsynaptic cell called dendritic spines. Dendritic spines are highly variable in their morphology and in their microanatomy (e.g. presence of subsynaptic organelles). It is

Connexin36 Expression in the Mammalian Retina: A Multiple-Species Comparison

open access: yesFrontiers in Cellular Neuroscience, 2017
Much knowledge about interconnection of human retinal neurons is inferred from results on animal models. Likewise, there is a lack of information on human retinal electrical synapses/gap junctions (GJ).

Quantification of the density of cooperative neighboring synapses required to evoke endocannabinoid signaling [PDF]

open access: yes, 2014
The spatial pattern of synapse activation may impact on synaptic plasticity. This applies to the synaptically-evoked endocannabinoid-mediated short-term depression at the parallel fiber (PF) to Purkinje cell synapse, the occurrence of which requires ...

The implication of a diversity of non-neuronal cells in disorders affecting brain networks

open access: yesFrontiers in Cellular Neuroscience, 2022
In the central nervous system (CNS) neurons are classically considered the functional unit of the brain. Analysis of the physical connections and co-activation of neurons, referred to as structural and functional connectivity, respectively, is a metric ...

Adenosine A1 receptor activation mediates the developmental shift at layer 5 pyramidal cell synapses and is a determinant of mature synaptic strength [PDF]

open access: yes, 2013
During the first postnatal month glutamatergic synapses between layer 5 pyramidal cells in the rodent neocortex switch from an immature state exhibiting high probability of neurotransmitter release, large unitary amplitude and synaptic depression to a ...

Rostral and caudal basolateral amygdala engage distinct circuits in the prelimbic and infralimbic prefrontal cortex

open access: yeseLife, 2022
Connections from the basolateral amygdala (BLA) to medial prefrontal cortex (PFC) regulate memory and emotion and become disrupted in neuropsychiatric disorders.

Determining the neurotransmitter concentration profile at active synapses [PDF]

open access: yes, 2009
Establishing the temporal and concentration profiles of neurotransmitters during synaptic release is an essential step towards understanding the basic properties of inter-neuronal communication in the central nervous system.

A population of immature cerebellar parallel fibre synapses are insensitive to adenosine but are inhibited by hypoxia [PDF]

open access: yes, 2011
The purine adenosine plays an important role in a number of physiological and pathological processes and is neuroprotective during hypoxia and ischemia.
