Overview

What is he best known for?

The fields of study he is best known for:

  • Cognition
  • Neuroscience
  • Classical conditioning

His main research concerns Classical conditioning, Neuroscience, Associative learning, Cognitive psychology and Basal forebrain. Peter C. Holland is interested in Latent inhibition, which is a field of Classical conditioning. His Neuroscience study typically links adjacent topics like Reinforcement.

His work on Discrimination learning as part of general Cognitive psychology study is frequently linked to Contextual learning, therefore connecting diverse disciplines of science. His research investigates the link between Basal forebrain and topics such as Cholinergic neuron that cross with problems in Stimulus. Peter C. Holland interconnects Basal ganglia, Central nervous system, Amygdaloid nucleus, Amygdala Central Nucleus and Substantia innominata in the investigation of issues within Amygdala.

His most cited work include:

  • Amygdala circuitry in attentional and representational processes. (504 citations)
  • Hippocampus and context in classical conditioning. (317 citations)
  • The amygdala central nucleus and appetitive Pavlovian conditioning: lesions impair one class of conditioned behavior (314 citations)

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

His primary scientific interests are in Neuroscience, Classical conditioning, Stimulus, Amygdala and Feature. Peter C. Holland has researched Neuroscience in several fields, including Reinforcement and Amygdala Central Nucleus. His Classical conditioning research integrates issues from Cognitive psychology and Central nervous system.

As a member of one scientific family, he mostly works in the field of Stimulus, focusing on Developmental psychology and, on occasion, Audiology. His work on Basolateral amygdala as part of his general Amygdala study is frequently connected to Physics, thereby bridging the divide between different branches of science. His study in Feature is interdisciplinary in nature, drawing from both Communication, Discrimination learning and Operant conditioning.

He most often published in these fields:

  • Neuroscience (61.54%)
  • Classical conditioning (50.00%)
  • Stimulus (28.85%)

What were the highlights of his more recent work (between 1999-2005)?

  • Neuroscience (61.54%)
  • Classical conditioning (50.00%)
  • Amygdala (25.00%)

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

His primary areas of investigation include Neuroscience, Classical conditioning, Amygdala, Stimulus and Basal ganglia. His Neuroscience study often links to related topics such as Amygdala Central Nucleus. The concepts of his Amygdala Central Nucleus study are interwoven with issues in Pattern discrimination and Cholinergic, Basal forebrain.

His research in Stimulus intersects with topics in Developmental psychology, Appetitive conditioning, Reinforcement and Audiology. Peter C. Holland has included themes like Feature and Communication in his Reinforcement study. His Basal ganglia research includes themes of Central nucleus of the amygdala, Arousal and Basolateral amygdala.

Between 1999 and 2005, his most popular works were:

  • The effects of amygdala lesions on conditioned stimulus-potentiated eating in rats. (94 citations)
  • Lesions of the Amygdala Central Nucleus Alter Performance on a Selective Attention Task (81 citations)
  • Trial and intertrial durations in appetitive conditioning in rats (68 citations)

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

  • Cognition
  • Neuroscience
  • Classical conditioning

Classical conditioning, Amygdala, Neuroscience, Appetitive conditioning and Central nervous system are his primary areas of study. His studies in Amygdala integrate themes in fields like Selective attention, Ibotenic acid, Amygdala Central Nucleus and Basal forebrain. Peter C. Holland works on Neuroscience which deals in particular with Cholinergic.

His Appetitive conditioning research incorporates elements of Developmental psychology, Stimulus and Audiology. Many of his research projects under Central nervous system are closely connected to Long-term potentiation with Long-term potentiation, tying the diverse disciplines of science together.
