A neuroscientific perspective on neurobiological differences in everyone

Classical conditioning links sensory input directly to changes in hormone-driven behavior. Operant conditioning links the rewards associated with the behavior to behaviors that are repeated, or not. We can think about which behaviors we don’t want to exhibit or don’t want to repeat.

Brain Activation Areas of Sexual Arousal with Olfactory Stimulation in Men

There is no direct link from visual or auditory stimuli that would explain any likelihood that spectral stimuli could classically condition the response to nutrient chemical associated with food odors.

No New Neurons for Smell?

Any study that indicates no olfactory bulb neurogenesis occurs in adult humans argues against the design in biology that ensures the plasticity of our brain-directed behavioral response to novel stimuli in our environment…

More than speculation: adaptive evolution in species from microbes to man

I’ve dismissed evolutionary theory that involves random mutations, and used the epigenetic effects of olfactory/pheromonal input on OR variants, which provide a clear evolutionary trail that can be followed from unicellular organisms to insects to humans,

Creation vs Evolution? Pre-existing genetic variation, not random mutation

The honeybee is an invertebrate model organism that exemplifies the vertebrate molecular mechanisms of evolution via pre-existing genetic variation, not random mutation, that are detailed here.

No fooling; visual appeal is not determined by what we see

Why is our response to other people enhanced by nudity? In other species with eyes, their visual response is enhanced by olfactory/pheromonal input.

They are what they eat, and so are we

Shall we use the honeybee as a model for the epigenetic effects of olfactory/pheromonal input across species from microbes to man?

Scents of Adolescence: Are you blind?

A flying mammal that relies on acoustic signaling for food acquisition helps make my case for the importance of olfactory/pheromonal input during the development of sexual preferences.
