  • Central nervous system

The scientist’s investigation covers issues in Neuroscience, Basal ganglia, Striatum, Substantia nigra and Globus pallidus. Neuroscience connects with themes related to Anatomy in his study. His Anatomy study combines topics in areas such as Anterograde tracing, Postsynaptic potential and Putamen.

J. P. Bolam interconnects Nucleus accumbens, Interneuron and Subthalamic nucleus in the investigation of issues within Basal ganglia. The concepts of his Subthalamic nucleus study are interwoven with issues in Cerebral cortex, Indirect pathway of movement and Central nervous system. The Substantia nigra study combines topics in areas such as Medium spiny neuron and Tyrosine hydroxylase.

His most cited work include:

  • Microcircuitry of the direct and indirect pathways of the basal ganglia. (884 citations)

  • Immunocytochemical localization of D1 and D2 dopamine receptors in the basal ganglia of the rat: Light and electron microscopy (490 citations)

What are the main themes of his work throughout his whole career to date?

J. P. Bolam spends much of his time researching Neuroscience, Basal ganglia, Substantia nigra, Striatum and Globus pallidus. He regularly ties together related areas like Subthalamic nucleus in his Neuroscience studies. His Basal ganglia study integrates concerns from other disciplines, such as Glutamate receptor, GABAergic, Anatomy and Thalamus.

His Striatum study also includes fields such as

  • Postsynaptic potential and related Dendrite and Cortex,
  • Putamen together with Striosome. His work deals with themes such as Cerebral cortex and Anterograde tracing, which intersect with Globus pallidus. J. P. Bolam has included themes like Ultrastructure, Immunocytochemistry and Axon in his Neuron study.

He most often published in these fields:

  • Neuroscience (71.76%)
  • Basal ganglia (46.56%)
  • Substantia nigra (36.64%)

What were the highlights of his more recent work (between 2011-2021)?

  • Neuroscience (71.76%)
  • Basal ganglia (46.56%)
  • Striatum (32.82%)

In recent papers he was focusing on the following fields of study:

J. P. Bolam focuses on Neuroscience, Basal ganglia, Striatum, Thalamus and Interneuron. His Neuroscience research includes themes of Movement disorders and Parkinson's disease. He is investigating Basal ganglia as part of his inquiry into Endocrinology and Internal medicine.

His study ties his expertise on Histamine together with the subject of Striatum. The study incorporates disciplines such as Choline acetyltransferase, Cholinergic, Cholinergic neuron, Nucleus accumbens and Pedunculopontine nucleus in addition to Interneuron. As a member of one scientific family, J. P. Bolam mostly works in the field of Dopamine, focusing on Neurotransmission and, on occasion, Pars compacta.

Between 2011 and 2021, his most popular works were:

  • A Major External Source of Cholinergic Innervation of the Striatum and Nucleus Accumbens Originates in the Brainstem (198 citations)
  • Deficits in dopaminergic transmission precede neuron loss and dysfunction in a new Parkinson model (177 citations)
  • The thalamostriatal system in normal and diseased states (151 citations)

In his most recent research, the most cited papers focused on:

  • Neuron
  • Neuroscience
  • Central nervous system

Striatum, Neuroscience, Laterodorsal tegmental nucleus, Optogenetics and Parkinson's disease are his primary areas of study. J. P. Bolam works in the field of Neuroscience, focusing on Pars compacta in particular. His studies deal with areas such as Neurodegeneration and Neurotransmission as well as Pars compacta.

His studies in Laterodorsal tegmental nucleus integrate themes in fields like Nucleus accumbens, Pedunculopontine nucleus, Cholinergic neuron, Interneuron and Choline acetyltransferase. His study on Choline acetyltransferase is covered under Cholinergic. His Optogenetics research is multidisciplinary, incorporating elements of Thalamus, Glutamate receptor, Glutamatergic, Deep brain stimulation and Basal ganglia.
