von Fersen L, Emmerton J, Delius J
Behav Processes
. 2014 Jun;
27(2):139-50.
PMID: 24924499
Pigeons were conditioned with a symbolic matching-to-sample paradigm. Six visual patterns in 16 configurations were presented in an operant chamber where reinforcement was delivered next to the correct keys. A...

Classical heart-rate conditioning and differentiation of visual CS with an appetitive UCS in pigeons
Klinkenberg T, Delius J, Emmerton J
Behav Processes
. 2014 Jun;
9(1):23-30.
PMID: 24923826
A tachycardic response was classically conditioned in thirsty pigeons using water as an unconditioned stimulus and localized lights as conditioned stimuli. This was successful in 6 out of 9 birds....

Delius J, Williams A, Wootton R
Behav Processes
. 2014 Jun;
1(1):15-27.
PMID: 24923542
Several brain sites in the pigeon were identified as maintaining electrical brain self-stimulation. Depending on the site, stimulus currents yielding maximal responding varied from 20 to 160 μA. A high...

Behav Processes
. 2014 Jun;
5(2):151-9.
PMID: 24897719
Pigeons with lesions involving the hyperstriatum accessorium, hyperstriatum intercalatus superior and hyperstriatum dorsale were compared with sham operated controls on acquisition of a simple colour/brightness discrimination. Correct and incorrect choices...

Delius J, Siemann M
Behav Processes
. 2014 Jun;
42(2-3):107-37.
PMID: 24897458
In order to survive and reproduce, individual animals need to navigate through a multidimensional utility landscape in a near-optimal way. There is little doubt that the behaviourally more advanced species...

Siemann M, Delius J, Wright A
Behav Processes
. 2014 Jun;
37(2-3):185-95.
PMID: 24897441
Fersen et al. (1991) (J. Exp. Psychol.: Anim. Behav. Process., 17: 334-341) trained pigeons to discriminate four overlapping pairs of stimuli A + B -, B + C -, C...

Gargiulo P, Acerbo M, Krug I, Delius J
Pharmacol Biochem Behav
. 2005 Jun;
81(4):732-9.
PMID: 15979133
In earlier studies it was found that glutamatergic transmission within the nucleus accumbens septi is involved in the performance of a learned visual shape discrimination in pigeons. This study examines...

Acerbo M, Godoy A, Delius J
Behav Pharmacol
. 2003 Dec;
14(8):631-40.
PMID: 14665980
The dopamine agonist apomorphine (apo) elicits stereotyped pecking bouts in pigeons, a response which increases with successive apo injections. The present study sought, first, to confirm the hypothesis that this...

Keller S, Delius J, Acerbo M
Behav Pharmacol
. 2002 Jul;
13(3):189-201.
PMID: 12122309
When repeatedly administered a dose of apomorphine (Apo), pigeons, much like rodents, show behavioural sensitization. In birds this sensitization expresses itself as an increasing pecking response to the drug and...

Psychopharmacology (Berl)
. 2001 Oct;
157(3):320-3.
PMID: 11605089
Rationale: The repeated administration of psychostimulants usually brings about a progressive increment of the behavioral responses that they induce. We examined to what extent this sensitization is due to an...
